Notes
via LIA to CXL: "Taping Compendium Volume 1" p 213-214 reviews a radio ad thus "The Cheetah Club commercial, with a 'Viola Lee Blues' background, is speculated to be bogus, alluding to an event on Friday, August 11. Directed specifically to hippies, the narration runs through the band's personnel line-up before giving the promo for the event." The Dead had left New York by the 11th to play Detroit that night.
