Bob Weir teamed with Slightly Stoopid at his own TRI Studios in Marin County, CA last night for a three-song collaboration that started with the Dead’s “Franklin’s Tower.”

Following that performance, Karl Denson, Fishbone frontman Angelo Moore, Weir and Slightly Stoopid teamed up for a cover of Prince’s “Purple Rain” in honor of his passing. Weir then stayed on for “The Rolling Stone” before departing.
