Donovan's Reef Jam was the only song Jerry played. The original Country Joe and The Fish were making their last tour (with Jack Casady replacing Bruce Barthol). For their last 3-night stand at Fillmore West, their various friends showed up. On the last set of the last night "everybody" showed up. This was released on a fine Vanguard CD (COUNTRY JOE AND THE FISH Live! Fillmore West 1969). As a footnote, KSAN-fm in SF (RIP) once broadcast the final number of either 1.9 or 1.10, an awesome Flying High with Mickey Hart and Dave Getz sitting in and that too is something else. The CJ Fish that played Woodstock was a different lineup entirely (except for Barry and Joe of course). Incidentally, second on the bill in January 69 was up-and-coming British Band Led Zeppelin.
