"Will you still need me, will you still feed me, when I'm 64." My gosh, he's THERE! When he did his 2002 tour, I read a lot about him because seeing his concert kept me in a cloud suspended over the earth for several months. I have the tour DVD which I can pull out to re-live it. He IS impressive - I'm so jealous of his 30-something wife!
BTW - there are DVD's available for the old Dick Cavett show, some of which feature John & Yoko. I'm anxious to see those courtesy of my Nexflix membership.
One of best things about getting older is the neat stuff you remember firsthand - like the Beatles! And the moon landing!
