We assign the known setlist material from the entire run to 5/30/73a for housekeeping purposes. The tape supplies all but the last two songs we list, which come from Davis 1973.
exante: Hilburn 19730519: "The Ash Grove has initiated a long, ambitious series spotlighting the vitality and influence of black music in America. ... On the way: Merl Saunders (with Jerry Garcia, May 29-30)".
Handbill also names George Tickner, but he is not on the one tape from this run, and b.m. review explicitly mentions quartet.
review: [undetermined show] b.m. 1973 finds the quartet, "sloppy and unrehearsed" as a group, but individuals giving "exact, tight and clean" solos.
