LONDON--Former Clash frontman Joe Strummer [ tickets ] has decided not to play at the upcoming Ian Dury [ tickets ] benefit to be held in London on June 16.

Strummer gave no official reason when he pulled out of the gig last Friday (5/12). A spokesperson for the benefit told LiveDaily, "I think [Strummer] may be sensitive about people getting the wrong idea that the Clash are to reform and doesn't want people buying tickets for the wrong reasons. It's a real disappointment as Joe was a major part of the bill. I know Ian Dury would have liked him to have participated." Strummer's name has now been taken off all artwork promoting the gig.

A piece in the U.K.'s Daily Mirror suggested that Strummer, Mick Jones and Topper Headon, who were all scheduled to perform separately at the show, would play a set as the Clash.

Published reports stating that former Clash bassist Paul Simonon had been added to the bill have also proved to be false.

Other stars performing at A Tribute to Ian Dury, which will raise money for the British cancer charity BACup, include Robbie Williams, former Sex Pistol Glen Matlock, Neneh Cherry and Kirsty MacColl.
