It's not the notes that are important here, it's the function of the harmony. check out both the Styne and Berlin scores and see if everything is identical, not just the melody. Use figured bass and roman numerals.
I didnt mind the film version of Rent, and I saw the show the first week it opened. I didn't HATE the Phantom movie, but it just didn't go anywhere, and whoever played the Phantom was really awful.
YF isn't a great show, it's not even a very very good show. It's a very tired formula and I was feeling almost offended, especially my intelligence. I adore the movie, but this show was made for the lowest common denom.
I'd be interested to know what those changes are. Anyone know? Also, does anyone else think this show really needs to be fully staged to be enjoyed? I do.
