My friend, Jerry Lightfoot, was the real deal and a real Texas Psych Legend. He formed a band with Michael Knust in 1969 and was the original Blieb Alien guitarist. He told me Billy was a total tool, a real hanger on type.
This guy has been sighted in close proximity to characters like Drummond, Lama, Lurkin, Sumnerd and more. This is the guy that helped keep Roky's solo royalties from him. Roky was living in poverty (in part) because of him. He sure did his part.
Anyway, get a good look at him above and stay well away. He plays some electric washboard-type instrument that just makes a bunch of noise. His mother sucks cock in hell too.
