I saw the Thursday evening performance, and while it wasn't the best thing I've ever seen, I will admit that it was a mostly-entertaining evening.
A chunk of the humor for me fell flat, but other people (My father [who prior to the show couldn't pick Martin Short out of a police line-up] included) was laughing at most of the sophomoric humor (Marc Shaiman's rear-end hanging out, etc.).
The company was quite good, stealing alot of the thunder from Short (I will admit, I am a big fan of Nicole Parker, dating back to her days as a member of an improv comedy troupe at Indiana University [go hoosiers!]), and most of the songs didn't suck. But here's my question (Marc are you still listening?) Why did Capathia's songs in the first act get cut? She only comes in at the tail end of act two, and I felt that she was totally under used. Oh well! Short review (no pun intended) not a complete a waste of time. For that, go see hot feet.
The one show everyone on Broadway is waiting to see: Twyla Tharp presents: Big Bottom - The Spinal Tap Jukebox musical!
