The real irony of Yoko is that the longer Paul lives, the longer she and her heirs will continue to make money until the Lennon/McCartney copyrights run out. So if Paul, God bless him, lives to be a 100, Yoko's great-great-grandchildren will still be making a whole lot more money off the Beatles than any Lennon musical.
It's too bad about the Lennon show. The Broadway reviews are all bad--most of them I read were from people who wanted to like the show, but felt there just wasn't enough "story" there--or too simplistic a story (for Broadway, no less).
Apparently there are nine cast members who play John--men, women, different ethnicities. Funny, the upcoming Dylan biopic has a similar deal with a bunch of different actors playing Bob. Wonder if it will be any better.
One reviewer did note that in the few appearances of the other three Beatles in the Lennon musical, they were played by females to John's male.
