I saaw BB perform a few years ago at his club in NYC. He was still outstanding, and he gave us more than our money's worth -- he must have played for three hours. He also used his American flag guitar strap and made some patriotic remarks that made some in the lefty crowd uncomfortable, so I admired him even more. Bless his soul.
B.B.'s the MAN!!!!!! He's one of my biggest influences as a guitarist (and just about every blues guitarist alive today.) First saw him play live ten years ago and was struck by his humility and appreciation for his audience. I even shook hands with him after the show, which was quite a thrill!
