Worth noting that this song was likely planned in advance, given all the evidence suggesting Trey was not "actually stuck", but that the entire event was an elaborate hoax. Recall, the band had performed as a fake band just months before on Halloween, the entire gag of Zamphir has no effective payoff unless something notable went wrong, Fishman says "you've all seen spinal tap, right?" (bassist stuck in shell), and the setlist of 12/30 Set 2 spells "TRS, TRS" (the rescue squad). Not that the band has ever spelled out any gags before, right?

#notStuck

Maybe not the greatest tune I've ever heard, but reasonably impressive under the circumstances nevertheless.
