We have scoured what listings are available for this Thanksgiving night, and not a single one of them bills anything at the Music Hall. That includes the following: Hayward Daily Review, November 22, 1974, p. 56 | "Rap Up's Wrap-Up," Oakland Tribune, November 24, 1974, p. 2-RAP |San Francisco Sunday Examiner and Chronicle Datebook, November 24, 1974, pp. 4, 7 and an ad in the same pink section, p. 5.
This is very unusual. The tapes are also out-of-pattern - on uncommon BASF stock in a stray tape box, recorded with the GD's Nagra (not Betty's), and labeling done by Betty. The latter was especially uncommon - Rex did most of the tape labeling in these days. They are clearly dated 11-28-74. So we aren't quite sure what to make of this.
