Sing Happy Birthday to your favourite programming language

  • 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.

    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?

    @MonkeyZeus Sorry, but taking length differences into account is intended. Since you don't have to be the shortest to gain popularity points, it shouldn't matter too much. There is also a tendency that programs written in a programming language that has a longer name, need less characters to implement the same functionality.

    I am no cross-programming guru but if 2 languages happen to achieve the goal in the same amount of logic bytes then it's kind of like getting penalized for getting your coffee from a "coffee shop" compared to a "café". Disclaimer: I am not a coffee connoisseur.

    Why all the upvotes for this despite all the downvotes for the Bonbon song? This is just as boring a challenge.

    @DavidFrank "Sorry, but taking length differences into account is intended. Since you don't have to be the shortest to gain popularity points, it shouldn't matter too much." Um, it's code golf, not a popularity contest. Votes are irrelevant and the shortest program wins. So you *are* being penalized for, e.g., writing in Microsoft Visual C++ rather than vanilla C (though, in that case, it's probably deserved).

    I should probably mention that the song is copyrighted and distributing these programs may cause a DMCA

    @DavidRicherby I'm sorry that the rules are not to your liking. I think this is more or less widespread practise to include the programming language name in the solution. Votes are not irrelevant (you gain xp by votes), though you might not win the contest. However, you have a free choice in your favourite programming language. In this contest not only solutions but also programming languages compete.

    @xnor Not sure, but people seem to like it any time you make them put their language name in the output.

    With the sheer number of answers, this seems to be more of a pop-con than code golf... How are you going to be able to find the shortest answer?

    @BetaDecay. Sorry i don't know the full etiquette yet. Comment deleted.

    @xnor Because the Bonbon song never made it to the HNQ.

    At least one of the answers prints a *leading* newline. Is that allowed?

    Hmm.. if anyone posts more than one answer to this question, they must be lying. It says to use your *favorite* programming language.

    It's 6 months to and from its birthday. Singing such is quite strange

    "Tasks that depend on a language's name are a form of disadvantaging some languages by arbitrary criteria." -- quote Martin Ender from this closed challenge.

    CJam, 46 42 bytes



    "Happy Birthday to You
    "___F<"Dear CJam
    "@


    How it works:



    "Happy Birthday to You
    "___ "Push "Happy Birthday to You\n" string to stack 4 times";
    F< "From the last string, take only first 15 characters. F is a";
    "Dear CJam "preinitialized variable whose value is 15";
    " "Push "Dear CJam\n" to stack";
    @ "Take the third string from end and put it to end";


    This leaves the stack as following at the end of the code:



    ["Happy Birthday to You
    " "Happy Birthday to You
    " "Happy Birthday " "Dear CJam
    " "Happy Birthday to You
    "]


    which are printed automatically to output as



    Happy Birthday to You
    Happy Birthday to You
    Happy Birthday Dear CJam
    Happy Birthday to You


    Try it here (Copy the code and run it)


    does the "first 15 characters" thing come from the F? is that how it knows the number 15?

    Yeah, a-f are 10-15.
