us that at last night's "Rise Above" concert in San Francisco, Henry Rollins invited Dead Kennedy's frontman Jello Biafra up on stage to announce the winner of the signed Rise Above guitar. Immediately following the announcement, Jello lent his vocals to the Black Flag's "Jealous Again."

(as this was a fan report, I don't have a very concrete source for this. If you were at the show, give us a shout)
