Saw the show in SF, enjoyed it, and can't say much more, as the creative team has apparently changed about 40% of what I saw for the NY audiences.
Here's some info regarding the changes made since SF from a Will Chase interview on Playbill.com:
Q: In Lennon, various actors play Lennon. How’s that work?
Chase: I’m now the narrator of the evening. Chad [Kimball] is the young John’s consciousness. Terry [Mann] is the mature John’s consciousness, and Michael [Potts] is more of John’s political consciousness. All of them kind of morph into me. I’m John Lennon if he were to show up on a given night and tell his story. This show isn’t a jukebox musical. It’s about John’s life using his songs, which he wrote about his life. Don Scardino’s vision for the show is really story theatre from the sixties and seventies. It’s so cool, and I think John would’ve totally dug it.
Q: How has the show changed since San Francisco?
Chase: It’s been tweaked and rewritten. It’s gotten a lot more in depth and emotional. Some songs have been moved or cut, and we’ve added others, like "Watching the Wheels" and "Mind Games." There’s much more about Paul McCartney and the Beatles in it now. And the ensemble has more of a voice."
Less "original concept" and more Beatles. Too bad.
