I recall some public television shows he hosted in the 1970's. I think there were three that I saw on the Chicago station. One was sea songs, one was about mining, and I forget the topic of the third show. His guests on the shows included BB king, playing an acoustic guitar, Tom Paxton, Jean Richie, The Beers Family (fist time I heard Dumbarton's Drums), Dave Van Ronk, Leon Bibb, and the rock band, McKendree Spring. I wonder if the shows were archived. I know PBS filmed some Philadelphia Folk festival programs from around the same time, and heard that the tapes were destroyed after the second re-broadcast by contractual obligation. I hope that wasn't the case with the Brand shows.
