Ryan Adams‘ ascent from poster boy to A-List celebrity continued apace in the early hours of yesterday (March 26) when he joined Elton John onstage in LOS ANGELES at the veteran’s lavish post-OSCARS bash.

Ryan Adams and Elton John worked together on a run through Elton John‘s classic ‘Rocket Man’. He had earlier played a half-hour set of his own material, including recent single ‘New York, New York’. The annual event, an AIDS fundraiser, was held at the Moomba restaurant.

Other guests included Oscar losers Paul McCartney and Sting plus P Diddy, Jon Bon Jovi, Kevin Spacey and Oscar winner Halle Berry. Ryan Adams was also spotted chatting to Bob Dylan, who came out for a rare public appearance.
