I saw it tonight. Didn't quite love it--a few of the jokes felt too cheap or easy, and there were moments I wished it was...more clever? Smarter? But I did laugh a lot, they made great use of the space, the vocals sounded terrific, and overall it worked. I did use the Playbill discount so got the standard ticket for $49 (plus fees), and definitely got my money's worth.
One of the funniest moments was one I don't think was scripted. When Cal gave Rose his jacket, instead of helping her put it on John Riddle said, "You'll have to put it on yourself. My mic just went out." Which seemed like a bitchy and in-character thing for Cal to say, but the Rose actress started laughing, and Riddle proceeded to carry a handheld mic through the rest of the show and during the singalong (I see in previous Instagram videos of it that he usually doesn't). Fit in perfectly with all the breaking-the-fourth-wall references (loved the line about striking the bench).
