some vinyl huh? wow, you are a fan. someone told me they saw him in New Jersey in 2004 and he wasn’t getting around very well. they were a smokin’ band when i saw them back in the 70s. there’s an interesting article about them at their website (a link at the bottom of the page)
i have a couple of cd’s Live Deep in the Heart of Texas and a King Biscuit show disk, both very good.
