Not recently, but I saw him 3 years ago at Bobby "Blue" Bland's 80th birthday celebration. B.B. didn't play his guitar. He just sat on a chair, told some stories, and sang. He was in fine voice though. Better than I expected.
Disappointing that he didn't play, but there were lots of great musicians on the bill, so it wasn't a big deal. It wasn't like it was a B.B. King concert. He was just one of many there to pay tribute to Bobby Bland.
