You have to love a movie that gives each band and song opening title credits that are as large as the ones for the actors. It make sense, since the music is more important than the plot. Also: the movie started with a card informing the viewer that the British version of the MPA gave it an X rating, which it earns with a single disconnected scene that features still images of very graphic sex.
Oh, and Sting has a couple scenes as a gas station attendant who likes the music of Gene Vincent.
