Grateful Dead - Sunshine Daydream, (DVD), Old Renaissance Faire Grounds,...

Looking back on those performances by The Warlocks and the Grateful Dead, is there a moment that jumps out at you?

Ken Babbs - Well, the classic one I think about all the time is “Dark Star” in 1972 out on the Creamery Field Trip [8/27/72]. That was unbelievable; there will never be anything like that again. The day, the acid, the music, everything—the heat! The guitars were all warped. We shot a hell of a movie! When we went to go show it to them, they all bitched and said that their guitars were out of tune, and they did not want it out there. I was like, “Shit...” [Laughs.]
