Eric, the lyrics used in the cut of "Class" that's on the soundtrack are different from the lyrics heard on the Broadway albums. In the book COLORED LIGHTS, Fred Ebb talks about how he wasn't allowed to use the lyrics he originally wanted for "Class" in the Broadway version, but he was happy he finally could use them in the film (I believe it's only the ending; in the film, we get "every guy is a snot/every girl is a twat/holy sh!t/holy sh!it/what became of class?" which in the Broadway version is the tamer: "everybody you watch/ has got a snake in his crotch/holy crap/holy crap/what became of class?").
"Some people can thrive and bloom living life in a living room, that's perfect for some people of one hundred and five. But I at least gotta try, when I think of all the sights that I gotta see, all the places I gotta play, all the things that I gotta be at"
