I saw it in La Jolla yesterday. It's an entertaining critic-proof jukebox musical in the same vein as Mamma Mia. The plot "excuses" for songs can be pretty lame. For example, a character is looking for a salt shaker so the plot can segue into the "Margaritaville" song ("Wasted away again in Margaritaville, searchin' for my lost shaker of salt.) The cast are all talented. The score is a Jimmy Buffet greatest hits collection. Lisa Howard is definitely the standout in the cast, taking her character beyond cardboard characterization.
I definitely expect more work to be done on the show before Broadway, especially the corny book which requires more genuine laughs. The La Jolla crowd was filled with Parrot Heads (Jimmy Buffet) fans, all of whom seemed to be of retirement age. Since the sets are made to tour, a limited run on Broadway could probably still recoup with the tour continuing to other cities.
For those of you who enjoy jukebox musicals and/or love Jimmy Buffet the show will be enjoyable. Those of you who are looking for a solidly constructed musical will be probably be disappointed.
"It does what a musical is supposed to do; it takes you to another world. And it gives you a little tune to carry in your head. Something to take you away from the dreary horrors of the real world. A little something for when you're feeling blue. You know?"
