Love all those guys! They are the longest running American rock group with the same lineup. Truly living legends...and the state congress voted them official Texas Heroes alongside Davy Crockett and Jim Bowie. But yes, Billy G. is the man. I'd actually never heard of Hendrix digging him or of any lost collaberations. I do have a cd with Hendrix and Jim Morrison doing a set. Some chaotic stuff going on there! Red House lasts 11:00 mins.
