 When deciding to give Donald OConnor (qv) a song, originally it  was "The Wedding of the Painted Doll". However, learning that  OConnor had a bag of tricks that he used in vaudeville, they  decided to use a song for OConnors comical background: Make Em  Laugh (Which the melody is supposedly from "Be A Clown" from  _Pirate, The (1948)_ (qv)).
