A mile away that same Friday, Chet Helms's Family Dog answered with FD-134: Spirit - the Los Angeles band with Randy California's guitar and Ed Cassidy's shaved head, riding their first album - over the Sir Douglas Quintet and Notes From the Underground, a Stanley Mouse poster (catalog, artist, bill, and the Aug 23-25 run per rockposters and the classicposters catalog record). Doug Sahm's Sir Douglas Quintet, Tex-Mex refugees who'd relocated to the Bay, and the Berkeley band Notes From the Underground filled out a bill that, like so many Avalon weekends, mixed a touring name with the local scene.
