Trey had stepped outside of his musical role with Phish before, with Bad Hat and New York!, but online video from this show demonstrates that this evening was more than an informal club gig. The first set featured novel lighting and set decoration, dancers, synth sound effects, and a full hour's worth of debut performances of original material. Trey acknowledges all the people who helped make this happen during "Last Tube", but there are not many creative people who also have enough ambition to bring so many ideas "from the root to the fruit"
"Wighat" is an interesting song in retrospect - Trey was 33 years old at the time, and it's not much of a stretch of the imagination to read the lyrics as a description of an party encounter during the looser Fall 1997 tour. I don't know if Trey was singing the line, "Can I live while I'm young?" with ironic understanding by that point, but it seems to have at least been on his mind.
