One of the major issues with the SF version was that the first act was NOT done chronilogically... He met Yoko a lot earlier in the first act and flashed back to his time with Cynthia and the Beatles...
In my opinion, it wasn't confusing. But a lot of people found it to be such, so there was MAJOR reconstruction done to the first act, with songs moved around and such
(if you want a list of the song changes, as of now, from SF to Broadway, you can click here:

I think Don did an AMAZING job turning the first act together and making it chronilogical and still keeping most of the information and songs intact. I saw it on July 8th before most of these current changes were implimented, and from what I hear, they're ridiculously unnecessary. I think Don will realize that and change most of it back. At least I hope so.
massofmen: the fact that this musical paints John as a MAN, with flaws and all, and NOT as a Saint is exactly what I like so much about this show! It's honest, and it's more raw (though some may argue not raw enough) than it would have been if it was a "praise John! He's God!" kind of thing. While it's also a biography, things have to be left out because, as someone stated in another post, it's a MUSICAL, NOT an A&E biography.
and as for what the "message" of the show is... I think it's all interpretation, but what I imagine they were going for was "Mankind is all connected, and we better work together as one or we'll never survive in this world." -- Most of the book is MADE of direct quotes that John said or wrote, so his words and philosophies, however changed or imperfect, are what drives the show.
it'll do better after the reviews come out (if they're good)
