Basketball Hall of Famer Bill Walton sat in with Gregg Allman on Sunday night at Humphreys Concerts By The Bay in San Diego. JamBase reports that Walton—a well known Deadhead and all-around music lover—took up percussion for the “One Way Out” that closed out the show.

Gregg Allman will return to the stage tomorrow night for the first gig of two-night run at the Uptown Theatre in Napa, CA.
