I have written two musicals. Though since I can't write music, all of the songs are parodies of other musical songs. One was a musical version of Super Mario Brothers (the video game, not the movie,) and the other is a parody of 42nd Street (the original, not the revival,) with parodies of all the songs and two versions of a gag on the audition dance.
So now you've met the court of 364, and if you ever wish to come...don't.
