Notes
According to DeadEssays blog A Rolling Stone report stated that the Dead, Musselwhite, Kaleidoscope, "and three other bands" played, and Blue Cheer are confirmed by a witness, so possibly only two of the other bands appeared. A poster for the benefit listed a completely different lineup - All Men Joy, Blue Cheer, Ace of Cups, Black Swan, and Creedence Clearwater Revival, which could be an early tentative list, or bogus.
