I saw it last week and very much enjoyed it. The book isn't perfect and has a few heavy-handed lines, but those can easily be cleaned up. The score is overall very strong, and it's nice to hear a set of lyrics that sound natural and easy to take in without cringing every other rhyme. The music is reminiscent of "City of Angels" and I truly hope it gets recorded.
The true strength is the cast, especially the wonderful Sally Mayes. I feel like she's found her best role (spoiler?) as a lesbian who likes to dress up in men's clothing! Her connection to the jazzy is evident and she possesses the right combination of vulnerability and harden anger to pull off the character.
To answer some questions, it is a traditionally structured musical. It's not a song cycle, and though some of the songs are performed as club acts some are also book songs, and even the club songs reflect the thoughts of the characters. It takes place in a nightclub, that's all...kind of like "Cabaret" in structure.
When I bought my ticket there was a discount code for $25 seats- don't know if that's still valid. It's certainly worth the money for Mayes' stellar performance.
Marie: Don't be in such a hurry about that pretty little chippy in Frisco.
Tony: Eh, she's a no chip!
