I just got done doing Les Miserables School Edition, we closed yesterday. I played Jean Valjean and I had no problems with the revised script. Yes, some lyrics and music were cut from Valjean's and Javert's face off after Fantine dies, but I don't think it hinders the show. Also, there are cuts made in "Castle on a Cloud," "Lovely Ladies," "Stars," and some of the battle stuff, but it all helps simplify the story to a better understanding.
I hold no grudges against the School Edition, I LOVED performing it. This show really is an honor to be a part of no matter where you do it or who you do it with. The music is gorgeous and everyone gets to show off so many of their talents.
Our cast didn't have much diversity in it either, except with ages. I did it with a Youth Company in Dallas. I hope you get what you're looking for and let us know how your show goes.
Break a leg!
