I just read an interview with Bruce Ian Douglas and he says that on their lp release (whichever of the first 2 lps) they played at the Filmore West. I will assume that this is the January concerts. Bill Gahram claimed that they were the worst band ever to play there. Bruce Ian Douglas agreed, yet later there was one heck of a show in Connecticut where they opened for Jefferson Airplane... and put them in diapers. It looks like Bill Graham recorded shows from all over the country. Is there any slight chance that this Ultimate Spinach/Jefferson Airplane show was recorded? Thanks for your time.
