Some old lists show Reconstruction at the Santa Monica Civic this date, but it seems highly unlikely that the band played the venue twice within six days, one of them on a Monday. The GD were also in the studio in NorCal, which certainly doesn't preclude a SoCal gig (back in those days one could buy a ticket at the SFO counter, run through "security", and be in an LA studio two hours later). But it does make it just a little less likely.
