I initially thought Bertha, but now I'm leaning more towards Fastrada. I don't know.
And I concur with "Chicago" being fine. I've seen the show seven times in touring productions through mostly Seattle, but also once in Tacoma, and once during it's Vegas stint, and I finally saw the Broadway production last year on Adam Pascal's last performance as Billy Flynn. I was worried because everyone and their mother was harping on how "tired" the show is on Broadway, but I thought it was still just as fresh as the first time I saw it (though I did not like Amara-Faye Wright as Velma, but that's more of a personal quibble more than anything).
Now a show that really is tired and has most of the cast sleep walking through a show was "Phantom" which I saw on Broadway back in June. Tempos and pacing was slow, and no one really had a hint of energy for most of the production. It was probably the most disappointing thing I saw out of the 28 Broadway or Off-Broadway shows I have seen over the last four years I have been going to New York (and that list includes "Spider-Man" version 2)
