I am SO EXCITED for this. The original concept album is one of my favorite musical scores in existence. I did see the U.S. version of this years ago and while I didn't hate it, I was open-mouthed "bzuh?" at the changes. And Tim Rice says on this website that this new concert version of this goes back to the original story and score as closely as it's ever likely to (he likes the addition of a few bits that have made it in there over the years, particularly Someone Else's Story).
It's airing on PBS on Wednesday. For those who need more motivation, lookit the cast, guys.
I might just pre-order the DVD unwatched.
