Merl Saunders is noted as participating in this big event at the SF Civic Auditorium, known variously as Black Quake or Black Expo '72. Be neat to see which day(s) he played, with whom, and what!
Oh yeah, this is the first time I have seen Night Times spell Merl's first name correctly - took them a year or so!
See also note on 5/28/72 Merl Saunders gig. Note as well my discussion of race in the "Jerry Garcia of Garcia-Saunders" post.
