Yankee Stadium was the site of two Paul McCartney concerts over the weekend. I last saw him perform at a Super Bowl Halftime Show several years ago and I knew - even from that brief performance at the football game - that he'd put on an outstanding full scale gig. And did he ever! Almost three hours on stage each night and the second night, he invited music legend Billie Joel, to join him for the first of two encores. Sir Paul is 69 years old but he still is vital and vibrant on stage - and he's getting ready to be married for a third time so there's no reason to stop putting on shows.
