I went to see Pete Seeger play last year. Figured it was a last chance. He's still going strong though, at 90, now. He didn't disappoint. His voice is somewhat weak and hoarse, but his banjo playing is still fine, and his ability to get the crowd singing (in harmony) is undiminished. Heck, he just has to wave his hand, and everyone joins in. He even taught the audience a new song that he had just written. Not a great classic, but catchy enough! I hope I'm still writing new songs at 89!
