Not a show review, and I'm not particularly a Smashing Pumpkins fan, but I happened to be reading the Wikipedia entry for the Smashing Pumpkins album "Gish". The entry references a Billy Corgan appearance on the radio show Rockline dated 7/13/1998, where he joked that the title of the album was going to be "Fish", but the title "was changed to avoid comparisons to jam band Phish". Personally, the only commonality that I find between Phish and the Pumpkins is each band's predilection for ingesting hallucinogens. But the Smashing Pumpkins were just getting going locally in the Spring of 1990 (they played Lounge Ax at least twice that year), so it's possible that they were in the audience on this night, watching Trey and Mike jump on trampolines and a very hairy Fishman play the trombone while wearing a muumuu. Or, they were too cool (or too poor) to attend, and they only heard about this show through friends that attended.
