@tomic601---Jim, this might interest you: The bassist on the backwaters album---Todd Phillips---and I were in the same band in '71, he leaving just as I was entering. He had decided to learn to play mandolin, and had arranged to study with David Grisman up in Marin County (about an hour drive north from our hometown of San Jose). David told him there were plenty of mandolin players, but a shortage of upright bass players. Todd was a Fender P-bass player, but took David's advice and got himself an upright. Todd ended up playing bass with David! And a lot of others. I last played with him about eight years ago, in San Jose.
