So glad to hear that he still puts on some good shows. I am a big fan and love his records and really enjoyed the movie he made with his daughter, but the only time I ever saw him live, about twenty some years ago at a small club near Kensington Market in Toronto, he put on an embarrassing show. He was drinking tequila and kept calling the waitress to bring him another and forgetting the words to the songs. His stories were not just rambling, but disjointed.
From the sounds of these posts, it sounds like I just caught him on a bad night. I'm glad it's not a regular thing.
