I also saw it in London and I think it would be a total flop in the U.S. It was mediocre at best. The score was completely forgettable, the choreography repetitive, and the book "and then he, and then I, and then they, and then he, and then, etc, etc. etc.." At the matinee I saw several people left at intermission. I saw this on the same trip I saw "Why Am I So Single" which was just as tepid, but in very different ways. Not a great trip for original British musicals.
