I hear ya @crustycool. One of my High School bands played "The Stumble", learning it off John Mayall’s 2nd album, with Peter Green taking Clapton’s place on guitar (Fleetwood Mac’s John McVie was at the time Mayall’s bass player). We hadn’t yet learned it was a Freddie King song. I never managed to see Freddie live, but I did Albert, who was fanf*ckingtastic!
Speaking of Little Walter, he’s still my Gold Standard, and Gary Smith’s as well. James Cotton lived and performed in the Bay Area for quite a while, drawn there by the healthy blues scene and audience. Musselwhite did too, but Butterfield moved to Woodstock, working with Levon Helm quite a bit.
