Bay seniors who missed last season’s hahaha production at the SF’s Marsh Theater of “Geezer” (no relation to yours truly) will be heartened to hear it is back until November 18. Geoff Hoyle, one of the City’s comic treasures, gives a solo performance exploring his idiosyncratically San Franciscan seniority. Saturdays at 3. Sundays at $7. Unreserved seating $25-$35.
