My 25th birthday Cabaret night (Trios in broadway shows, for women)?

My friends that are employees at the Arc and they are women would like to sing some songs from broadway shows. only thing I knew is "You Could Drive a Person Crazy" from Company(Pat, Jill, Carmen, and Kim) and "You Gotta Get a Gimmick" from Gypsy (three women with the same name Debbie)
