This show is an early-era scorcher that took place only two days before the legendary Ian Hebron's Farm

After the excellent Bold as Love and Bag opening twofer, a few people call for Bathtub Gin, so some of the band's friends have clearly heard the song this performance, the earliest version that circulates. Between songs some amusing banter includes Trey complaining that the drums are too loud.

The straightforward Mike's Groove that follows starts with a lot of bass and drums in the first solo before Trey enters. Mike's backing vocals on the Weekapaug adds the only truly unique touch to a solid early version.

A girl requests Sanity and they play that early fast version, which sounds like a completely different song than the traditional powerhouse we're used to. Page takes the lead during the last two jam segments and it's a refreshing change.

Trey invites Nancy Wright up to sing on Halley's, which is the second to last version before the song's 4-year retirement.

The YEM has to be heard to appreciated, with Trey getting completely enveloped by the song, his fiery soloing eventually building up to machine gun bursts that include brief teases of the theme to "My Soul".

More amusing banter precedes "Lazy Lester", which appears to reference a person/band that is going to be playing the venue the following week. Though it doesn't go really deep, this Bowie has smooth, sharp playing by the entire band, especially Trey.

The intro to this early Mango Song is slightly different than later-era versions, but it cuts just before the end on the tape I listened to, cutting to Melt at the first chorus.
The Gin is very straightforward as is the remainder of the show. Worth a listen for sure.
