Notes
LIA comment via August 19-September 4, 1967 (Forces Tear Loose From The Axis) quotes McNally: "The Dead were to play on August 20 at a gathering on beautiful, holy Mount Tamalpais, but when they got to the mountaintop, they discovered that there was no power, and the event turned into what Rifkin would call 'a bongofest.'"
