Your favourite programming language has just had a birthday. Be nice and sing it the Happy Birthday song.

Of course you should accomplish this by writing a program in that language. The program takes no input, and writes the following text to the standard output or an arbitrary file:

Happy Birthday to You
Happy Birthday to You
Happy Birthday Dear [your favourite programming language]
Happy Birthday to You

You should substitute the bracketed part (and omit the brackets).

This is a code golf — shortest code wins.

UPDATE

I'm glad that the question aroused great interest. Let me add some extra info about scoring. As stated originally, this question is a code golf, so the shortest code is going to win. The winner will be picked at the end of this week (19th October).

However, I'm also rewarding other witty submissions with up-votes (and I encourage everybody to do so as well). Therefore although this is a code-golf contest, not-so-short answers are also welcome.

Results

Congratulations to Optimizer, the winner of this contest with his 42 byte long, CJam submission.

    \$\begingroup\$ Can we count the name of the programming language as one byte because it would only seem fair to people coding in a long-winded language such as JavaScript vs. someone doing it in C. We are really looking for most creative logic right? \$\endgroup\$ – MonkeyZeus Oct 13 '14 at 18:49

    \$\begingroup\$ Why all the upvotes for this despite all the downvotes for the Bonbon song? This is just as boring a challenge. \$\endgroup\$ – xnor Oct 14 '14 at 7:15

GolfScript, 49 bytes

Just a blatant port of the CJam answer.

"Happy Birthday to You
"...15<"Dear GolfScript
"@

Try it online!

Wren, 78 bytes

I have forgotten about Wren so I'm trying to use it.

Fn.new{(1..4).map{|i|"Happy Birthday "+(i==3?"Dear Wren":"to You")}.join("

Try it online!

JavaScript (84 76 bytes)

x=`Happy Birthday To You\n`,alert(x+x+`Happy birthday Dear JavaScript\n`+x)

Output:

Happy Birthday To You
Happy Birthday To You
Happy Birthday Dear JavaScript
Happy Birthday To You

Short language name to the rescue!

W is just 0.0833 years old but I'm still posting this ... Insanely long but oh well.

Explanation

4                                       E % Foreach in the range from 1 to 4:
 "Happy Birthday "                        % Append the string "Happy Birthday "
                  a3=                     % If this is the third line:
                     "Dear W"&            % Output "Dear W"
                              "to You"|   % Otherwise, output "to You"
                                       +  % Join the two strings.
