Uncle Pen and My Sweet One through Rocky Top featured Russell Flanigan on fiddle. Trey quoted Fixin' to Die in the ending chorus of Antelope. Trey flubbed the lyrics to Cavern. This show featured the first known Phish performance of Let's Go, which replaced HYHU. After the second Let's Go, Trey introduced the crew (with Page providing "Charge!" teases) and dedicated Mike's Song to "Mindy" and the "spirit of Ian in the back of the room." Pete Schall's name was spoken in the Mike's intro. Page teased Fishin' Hole (aka The Andy Griffith Show theme) during Hydrogen. Trey quoted and teased Groove is in the Heart in Weekapaug Groove. A recording of Antelope through Rocky Top also circulates as 9/17/90, but it is believed that 2/4/91 is the correct date for this portion of the setlist.
