Guns N’ Roses performed a rare Sex Pistols song live for the first time Saturday night during their concert in Fortaleza, Brazil. Midway through their 27-song set, bassist Duff McKagan led the group through “Black Leather,” an outtake from the Sex Pistols’ 1979 The Great Rock ‘n’ Roll Swindle soundtrack.

Guns N’ Roses covered the song on their 1993 album The Spaghetti Incident?, with Axl Rose and not McKagan on vocals.
