update: see also a subsequent list from 1973-end
11/2/70 (Monday): Jerry Garcia / BBHC / Ice / Cleveland Wrecking Company. Harding Theater. Benefit for A Learning Place. I don't know if this would have been NRPS or JGMS; I am listing as JGMS for no particular reason.

1/5/71 (Tuesday): JGMS at Matrix

2/4/71 (Thursday): JGMS at Matrix
! listing: San Francisco Examiner, February 4, 1971, p. 25.
3/30/71 (Tuesday): NRPS at Matrix. I interpret this as warmup for the east coast tour. BTW, they also played the next night, according to a redacted source, so we can add 3/31/71 (Wednesday), same band and room.
! listing: San Francisco Examiner, March 30, 1971, p. 24.
11/24/71 (Wednesday): JGMS at Keystone Korner. Garcia's first-known gig for Freddie Herrera had happened the night before Thanksgiving the year before with the New Riders. Jerry and Merl reprise the gig on its first anniversary.

1/18/72 (Tuesday): JGMS at Lion's Share
! Listing: San Francisco Examiner, January 18, 1972, p. 21.
3/1/72 (Wednesday): JGMS at Keystone Berkeley (formerly New Monk). I now understand this to be the very first night for the so-named Keystone at the corner of University and Shattuck. It's a fitting indicator of the centrality of Garcia to Freddie's enterprises that he would play this opening night at the old Monk. (See also "Jerry and Freddie, mid-March 1972".)
! Listing: San Francisco Examiner, March 1, 1972, p. 33.
6/3/72 (Saturday): JGMS at Keystone Korner
! Listing: San Francisco Examiner, June 3, 1972, p. 10.
8/31/72 (Thursday): JGMS at Keystone Berkeley
! Listing: San Francisco Examiner, August 31, 1972, p. 31.
12/26/72 (Tuesday): JGMS at Keystone Korner. This one puzzles me, because the KK would have been under Barkan's ownership at this point. Barkan has narrated that he once hosted Jerry and Merl (after he started booking the room on July 7th), but didn't dig the vibe and stuck thereafter with jazz. This could well be that very gig. I still don't know what to make of a listing for JGB at KK four years later, of course ...
