It appears that we have established that the tape circulating labeled "Hells Angels Benefit, Anderson Theater, NYC 11/23/70" cannot possibly be from that date
and the strong likelihood that this tape in fact comes from Fillmore East 11/16/70, mastered by the same people who gave us the surreptitious masters of 2/11, 13 &14/70, 5/15/70, and 9/18-19-20/70. Two questions now come to mind: How did this tape get into circulation mislabled in the first place, from the mid 70s at the latest? Where is the rest of 9/18/70 and 9/19/70? Note that the other 1970 surreptitious SBDs were in circulation properly labeled from very early on. 3/5s of 5/15/70 was broadcast on KPFA on 6/21/71; this was probably Allan Mande's doing. Large parts of the February shows and 9/20/70 have also always circulated, whereas the hour-long portions of SBD we have for 9/18/ & 9/19/70 only came into circulation in the 90s. Where is the rest of these shows?
