Confirmation:
Audience recording
-- we're fairly confident this audience recording labelled "Sundance" is actually this show on 22nd. The band talks about this show being their last of the tour.

PattonTrader quotes this date as "January 20, 1990 Philadelphia (PA)."
Old FNM trade list quotes this date as "Bayshore, NY".
This article suggests Philly played after Boston, which would make it the 22nd.

The Philadelphia Inquirer, 24 Jan 1990, page 5D - gig review

There is an audience recording sometimes mislabelled as 20th January that is likely this show as the band talk about it being their last show.

Description:
From Soundgarden Live Guide:
"Mike Patton of Faith No More sings "I Awake" while Chris crowd surfs. At the end of Faith No More's set, Soundgarden and crew join them for a cover of Black Sabbath's "War Pigs"."
This show included a "massive food fight" - Tampa Tribune, 2 Feb 1990, page 5F

Before The Crab Song: "How about an old song?"

"You guys having a good time yet? That's just great, coz if you don't look good, we don't look good."
"You may not know it, but this is our soundman's last night with us, he doesn't know it either yet, Noodle, we never really liked you anyway, you fucking son of a bitch, you may as well go home now, this is for you."

Huge response from the crowd for Sweet Dreams cover.

Before War Pigs:
- Jim: Please Satan kill us all, but them first so we can watch and jack off
