Code Johnny Code, Code!

Question

Rock-and-roll founding father Chuck Berry sadly passed away today.

Consider the chorus of his famous song "Johnny B. Goode":

Go, go
Go Johnny go, go
Go Johnny go, go
Go Johnny go, go
Go Johnny go, go
Johnny B. Goode

^{(There are other ways it has been punctuated but the above will serve for the purposes of the challenge.)}

Challenge

Given a nonempty, lowercase string of letters a-z, output the chorus of "Johnny B. Goode" with all the instances of Go or go replaced with the input string, capitalized in the same way.

A trailing newline may optionally follow. Nothing else in the chorus should change.

For example, if the input is code the output must be exactly
Code, code
Code Johnny code, code
Code Johnny code, code
Code Johnny code, code
Code Johnny code, code
Johnny B. Codeode
optionally followed by a newline.

Note that the capitalization of all words matches the original chorus, and (despite lack of rhythm) the Go in Goode is replaced as well as the individual words Go and go.

The shortest code in bytes wins.

Test Cases

"input"
output

"go"
Go, go
Go Johnny go, go
Go Johnny go, go
Go Johnny go, go
Go Johnny go, go
Johnny B. Goode

"code"
Code, code
Code Johnny code, code
Code Johnny code, code
Code Johnny code, code
Code Johnny code, code
Johnny B. Codeode

"a"
A, a
A Johnny a, a
A Johnny a, a
A Johnny a, a
A Johnny a, a
Johnny B. Aode

"johnny"
Johnny, johnny
Johnny Johnny johnny, johnny
Johnny Johnny johnny, johnny
Johnny Johnny johnny, johnny
Johnny Johnny johnny, johnny
Johnny B. Johnnyode

"fantastic"
Fantastic, fantastic
Fantastic Johnny fantastic, fantastic
Fantastic Johnny fantastic, fantastic
Fantastic Johnny fantastic, fantastic
Fantastic Johnny fantastic, fantastic
Johnny B. Fantasticode

Let's just observe a minute or two of silence, and wish Rest In Peace to Chuck. — Erik the Outgolfer, Mar 19, 2017 at 19:51

yw~hC<Ctrl-R>", <Ctrl-R>0<Enter>Johnny B. <Ctrl-R>"ode<Esc>}O<Ctrl-R>", Johnny <Ctrl-R>0, <Ctrl-R>0<Esc>3.

Start with the word on a line on a file with the cursor at the first character, then this will replace it all with the text Explanation

Copy the word into a register, then change the first letter to be capitalized and save that to a register.
Write the first line using the registers to fill in the replacements and last lines
Write the second line using the registers to fill in the replacements
Repeat the middle line 3 times

JavaScript, 98

s=>[S=s[0].toUpperCase()+s.slice(1),[,,,].fill(` ${s}
${S} Johnny `+s)]+`, ${s}
Johnny B. ${S}ode`

Abuses array-to-string serialization to create commas. Builds an array of the form:

["Go",
 " go\nGo Johnny go", (repeated...)]

And concatenates it to the string of the form ", go\nJohnny B. Goode":

["Go",
 " go\nGo Johnny go",
 " go\nGo Johnny go",
 " go\nGo Johnny go",
 " go\nGo Johnny go"] + ", go\nJohnny B. Goode"

JavaScript (ES6), 104 101 99 bytes

(i,u=i[0].toUpperCase()+i.slice(1),x=`, ${i}
${u} Johnny `+i)=>u+x+x+x+x+`, ${i}
Johnny B. ${u}ode`

Previous version:

(i,u=i[0].toUpperCase()+i.slice(1))=>u+`, ${i}
${u} Johnny ${i}`.repeat(4)+`, ${i}
Johnny B. ${u}ode`

How it works:

It's an anonymous function that takes the input as the parameter i
Defines a variable u as the input i with the first letter capitalized (Note that this assumes input is nonempty, which is OK)
Just directly construct the string to be returned from those two variables.
Repeating the string "go, \nGo Johnny go" four times instead of repeating "Go Johnny go, go" saves one byte.

Edit 1: Forgot to golf out the semicolon, haha!! Also miscounted the bytes, it was originally 102, not 104. Thanks apsillers.

Edit 2: Instead of .repeat(4), by putting that string in a variable x and doing x+x+x+x allows saving two bytes.

Test snippet

let f = (i,u=i[0].toUpperCase()+i.slice(1),x=`, ${i}
${u} Johnny `+i)=>u+x+x+x+x+`, ${i}
Johnny B. ${u}ode`;

<input id=I type="text" size=70 value="code"><button onclick="console.log(f(I.value))">Run</button>

It's a start. Can hopefully be reduced further.

Basically it's an anonymous function which takes a string input and then uses regex to create the required output.

@(a)                                                    %Anonymous Function
    regexprep(                                          %Regex Replace
        ['1, 2' 10                                      %First line is: Code, code
            repmat(['1 32, 2' 10],1,4)                  %Then four lines of: Code Johnny code, code 
                               '3B. 1ode'],             %Final line: Johnny B. Codeode
         {'1','2','3'},                                 %1,2,3 are our replace strings in the lines above
         {[a(1)-32 a(2:end)],a,'Johnny '}               %We replace with '(I)nput', 'input' and 'Johnny ' respectively.
    )

An example:

@(a)regexprep(['1, 2' 10 repmat(['1 32, 2' 10],1,4) '3B. 1ode'],{'1','2','3'},{[a(1)-32 a(2:end)],a,'Johnny '});
ans('hi')
ans =

Hi, hi
Hi Johnny hi, hi
Hi Johnny hi, hi
Hi Johnny hi, hi
Hi Johnny hi, hi
Johnny B. Hiode

~~You can sort of Try it online!. The code doesn't quite work with Octave as all the upper case letters become ${upper($0)}, whereas in MATLAB this is converted to the actual upper case letter.~~

Given the input is guaranteed to only be a-z (lowercase alphabet), I can save 22 bytes by using a simple subtraction of 32 to convert the first letter in the string to capital, rather than using regex with the upper() function.

As a result, the code now works with Octave as well, so you can now Try it online!

Nova, 105 bytes

a(String s)=>"#{s.capitalize()+", #s\n"+"#s.capitalize() Johnny #s, #s\n"*4}Johnny B. #s.capitalize()ode"

Because Nova (http://nova-lang.org) is extremely early beta (and buggy), there are some obvious handicaps that are in place here keeping it from using even less bytes.

For example, could have saved capitalized function call (which is called 3 times) in a local variable like this:

a(String s)=>"#{(let c=s.capitalize())+", #s\n"+"#c Johnny #s, #s\n"*4}Johnny B. #{c}ode"

which would have taken the byte count down to 89 bytes. The reason this doesn't work now can be blamed on the argument evaluation order in the C language, because Nova is compiled to C. (The argument evaluation order will be fixed in a future update)

Even more, I could have introduced a "title" property in the String class (and I will after doing this lol) to reduce the count from the capitalization function call:

a(String s)=>"#{(let c=s.title)+", #s\n"+"#c Johnny #s, #s\n"*4}Johnny B. #{c}ode"

and that would free up 7 bytes to a new total of 82 bytes.

Furthermore (and further off), once lambda variable type inference is added, this would be valid:

s=>"#{(let c=s.title)+", #s\n"+"#c Johnny #s, #s\n"*4}Johnny B. #{c}ode"

The count could be brought down to 72 bytes.

By the way, this is my first code golf, so I probably have missed even more optimizations that could have been made. And this being a non-golf centric, general purpose language, I think it's pretty impressive.

The first 105 byte code works in the current Nova Beta v0.3.8 build available on http://nova-lang.org

class Test {
    static a(String s)=>"#{s.capitalize()+", #s\n"+"#s.capitalize() Johnny #s, #s\n"*4}Johnny B. #s.capitalize()ode"

    public static main(String[] args) {
        Console.log(a("expl"))
    }
}

outputs:

Expl, expl
Expl Johnny expl, expl
Expl Johnny expl, expl
Expl Johnny expl, expl
Expl Johnny expl, expl
Johnny B. Explode

Thank you for listening to my shameless advertisement for the general purpose language Nova (found at http://nova-lang.org ...get it now!!)

v1.2 - - 2 bytes - Swapped (i)=> for i=>, thanks to TheLetalCoder comment.
v1.1 - -29 bytes - Thanks to Sir Bitesalot last update, who remembered me I could edit the string before format.
v1.0 - 159 bytes - Initial solution.

Notes

The title has a link to a page with the code and the test cases. Just hit Go and the result will be printed below the code.

No need for the () around the argument for the Func just do i=>. You can probably also make use of interpolated strings from C# 6 and lose the string.Format although I haven't looked at the code too much to see how (should be trivial). — TheLethalCoder, Mar 21, 2017 at 17:28
I can drop the (), but I doubt that I can make use of interpolated strings without boosting up the size of the code, due to the replace that happens to collapse the repetition. — auhmaan, Mar 22, 2017 at 11:03
Like I said I was being lazy and hand't actually tried anything myself! Was just a suggestion to look into. — TheLethalCoder, Mar 22, 2017 at 11:04

Excel VBA, _{137 121 112 89 87} 84 Bytes

Anonymous VBE immediate window function that takes input of type Variant/String from cell [A1] and outputs by printing the the VBE immediate window

c=[Proper(A1)]:s=vbCr+c+[" Johnny "&A1&", "&A1]:?c", "[A1]s;s;s;s:?"Johnny B. "c"ode

-16 Bytes for converting to Immediate window function

-9 Bytes for using [PROPER(A1)]

-23 Bytes for dropping For ... loop and abusing the ? statement

-2 Bytes for replacing " Johnny "&[A1]&", "&[A1] with [" Johnny "&A1&", "&A1]

-3 Bytes for using + over & for String concatenation and leaving the terminal string unclosed

Example Case

[A1]="an"          ''  <- Setting [A1] (may be done manually)
                   '' (Below) Anonymous VBE function

\$\begingroup\$ @BruceWayne, nice cape. VBA is supports autoformatting, which means that things like ?,i=1To and &c are digested into more verbose but readable terms like Print, i = 1 To and & c. The community has decided that the compressed version of code in languages is acceptable for responses (see codegolf.meta.stackexchange.com/questions/10258/… ) \$\endgroup\$

\$\begingroup\$ @BruceWayne As for ?, I believe it is a remnant from old version of Excel (4.0 and below) where Macro Sheets were used in place VBA via the VBE where it was used as a keyword for printing a string provided after it to a pre-indicated text file. The ? keyword itself is still very useful for code golfing as the Print keyword is used to write strings to a text file in current versions of VBA. Note, I am going off of memory with one so take that with a grain of salt. \$\endgroup\$

Longest part of it is the format for printf. There are problems with input different than string from a to z(yes I know I don't need to support anything else).

    public static void main(String[] a) {
