Oh, and I didn't realize until I got there, but the guy who cowrote the book and music is a veteran of the Neo-Futurists, most famous for their play "Too Much Light Makes the Baby Go Blind" - which, in turn, is famous among those I know for it's segment that was later turned into an animation entitled "Bingo." This explains a lot, including the surreality and tongue-in-cheek humor in which the play makes fun of itself.
Just go see it already. It's playing at the OCPAC for the moment, and looks like it'll hit Los Angeles in a couple of weeks.
