Duff McKagan & Axl on stage together after 2 decades ?!?

The first video of Duff McKagan’s surprise performance with Guns N’ Roses Thursday night at London’s 02 Arena has surfaced.

Duff played four songs with the band: “You Could Be Mine,” “Nice Boys” (Rose Tattoo cover), “Knockin’ On Heaven’s Door” (Bob Dylan cover) and “Patience.”

McKagan played bass on “You Could Be Mine,” switched to guitar for the two covers, and then worked the tambourine on “Patience” during the encore.
