YouTube user "Nosmo King" has uploaded for the first time footage of Phish playing with Santana, captured on July 31, 1992 at Blossom Music Center in Cuyahoga Falls, OH. The setlist has been added to phish.net and you can watch the video here:
The entire band sat in for "Elmore's Blues," and Trey stayed on for "Blues for Salvador." At one point, Santana comically introduces Mike as "Mark." Thank a taper!
