Oh! Calcutta!: Based on the controversial off-Broadway musical comedy revue, "Oh! Calcutta!" is a series of musical numbers about sex and sexual mores. Most of the skits feature one or more performers in a state of undress, simulating sex, or both. The show sparked considerable controversy at the time because it featured extended scenes of total nudity, both male and female. The title is taken from a painting by Clovis Trouille, itself a pun on "O quel cul t'as!" French for "What an arse you have!".
