Duff McKagan rejoined Guns n Roses in Buenoes Aires Sunday for the first of 5 shows he'll do with GnR.

Axl Rose introduced him saying

Our regular bass player, Mr. Tommy Stinson, is doing a show at Coachella with The Replacements, so we had to try to find a new guy.” “He's hanging in there. [Please give] a hearty welcome to the new guy, Mr. Duff McKagan."

Duff played bass and handled lead vocals on a couple of cover songs; "Attitude" by The Misfits and "Raw Power" by The Stooges!  Duff said:

It's pretty great to play these songs again, and looking forward to playing some gigs with my pal again.”  “South America is always a radical place for rock n roll...and I'm honored to be doing this thing, in that place."

So far no American dates for "Duff n Roses" have been set but, you can see part of the big reunion show and hear Duff do the cover songs in the vids below!  Careful, lyrics are NSFW!
