My old HS did A Chorus Line.
The director played Diana in national tours and international casts. So needless to say they used original choreography - and she worked the hell out of them.
The significant changes made were "This and That."
Mark's Gonorrhea verse was cut. "I got hard" was cut.
Choice words, mostly from Val were changed.
Paul's monologue remained intact. Homosexuality was not cut in any way.
They wanted to keep as much as they could and got away with a lot for being a HS.
"Zac is sweet as can be. He's very much just a sweet kid from California who happens to have a face that looks like it was drawn by Michelangelo, (if Michelangelo did anime)."

"I haven't left this building since Windows 3.1!"
"Celebrating a birthday this week: Rene Descartes is 412! Do you know who he is? Then why are you watching this show? You could probably get into college and even get one of those job things. As for the rest of us; Amanda Bynes is 22! Yay!"
-E!'s "The Soup"
