Duff Mckagan stunned GUNS N' ROSES fans in London on Thursday night (14Oct10) when he joined former bandmate Axl Rose on stage for a show at the 02 Arena.
The bassist, who recently quit Jane's Addiction, performed You Could Be Mine, Nice Boys and Knockin' On Heaven's Door with Rose's latest Guns line-up.
MCKagan has rejoined his other former Guns N' Roses bandmates, Matt Sorum and Slash, in supergroup Velvet Revolver.
The band has been out of commission since frontman Scott Weiland was fired last year (Apr09), but now they've revamped their search for a new singer.
