I tried (not all that hard) to find more recent status for Chess in the States, but I ended up finding (again) only this cache of a page that indicates that the only version of the show that can legally be performed in the States is the horrible Broadway re-write. The Yahoo discussion group seems to be members-only, and I don’t quite feel energetic enough to sign up and see what more recent info might be available. Bad blogger, I am. No biscuit.
I was able to see a "concert" of the show, wherein talented people sang the songs and discussed the action between the songs, but no actual acting took place. The flow and music were clearly not from the horrible Broadway re-write, and it was a good show (I believe they said in the Q&A afterwards it was a mélange of the West End, US, and Australian versions). I did hate my fellow east-siders, though, for their audible consternation when the word "fuck" was uttered. Not quite as much as I hated the Seattleites at ACT when several of them said a line in the play along with the actor. And no, it wasn’t a production of The Rocky Horror Show.
