A few years ago, I played at a festival for which Pete Seeger was the headliner. Man, what a guy -- very gracious and unassuming to everyone. He wanted to know the bus schedule that would get him from the train station to the festival ground because he didn't want to put anyone to the trouble of coming to pick him up. He invited all the other performers up on stage to sing with him on one of his final songs. I've had some great performing experiences, but that one I'll never forget.
