This comes from the Dead Kennedys website:

Seminal punk rock band Dead Kennedys announced today that they are extending an offer to former lead singer Jello Biafra to rejoin the band at their 25th Anniversary concert at the Key Club in Los Angeles on August 19th, 2003.

"We are absolutely serious in asking Jello to rejoin the band on our anniversary," said Dead Kennedys bassist Klaus Flouride. "This is not a prank or a publicity stunt. Last evening we sent word to Biafra and his representatives informing him of this offer. We wanted to make sure he was informed in advance, so he knows that we are serious in asking for him to participate. We'd love it, and I think the fans would love it, if we could just bury the hatchet."

"This isn't about nostalgia," said Dead Kennedys guitarist East Bay Ray. "There are serious problems in the world right now and Dead Kennedys' message of questioning authority and thinking for yourself is more important than ever before. Maybe we could settle our differences and play together while we are all still able to do so."
