I WISH they were taking my advice, but given the Weissler's history of NOT doing fiscally responsible things, I think they simply realized they were going to get creamed by the NY crix, and that Christina was really making noises about enforcing her contract so that she could open the show.
I've also heard that the production was truly bad. They had all this revisionism going on, and all these "fixes" they put in, including a couple of new songs, cutting the entire first scene and song, and deleting I Love to Cry at Weddings, and turning Rhythm of Life into some kind of hip hop number. In the last couple of weeks they'd realized that these "fixes" were not fixing anything because the original show was not broke. So, one by one they were putting the show back the way it was - a good deal of the opening scene was restored, the replacement for I Love to Cry at Weddings was replaced with I Love to Cry at Weddings, and on and on. These people need to stop hiring people who have no respect for the vehicle their reviving. They need to hire people who understand the show they're doing, and who don't think they're better or smarter than the better and smarter people who originally put the show together.
