I saw the show last night. Very fun and wonderful performances from everyone. The scenic designs are cheap looking, but they were serviceable. It was a rare treat to have a full orchestra. Megan did a terrific job and the audience loved her. Her voice in the show is similar to the speaking voice I have heard her use in various video clips at NYCB, so she is not feigning the cute little voice. For my money, I was blown away by the actress that played Hildy. Great voice, perfect comic timing and a charismatic stage presence. Jackie Hoffman had some terrific, scene stealing schtick. Go and enjoy.
As an aside, I saw former lead NY Times dance critic Anna Kisselgoff in the audience last night.
