At Thursday's Firenze Rocks Festival set in Florence, Italy, Foo Fighters invited little band called Guns N' Roses onstage to perform the brilliant It's So Easy.
This isn't the first time the two rock titans have overlapped, of course; most notably an injured Axl famously borrowed Dave's iconic guitar throne, which was created for 'The Broken Leg Tour' after the Foos leader tumbled off a stage in Sweden and broke his leg.
Thankfully this performance had absolutely no broken bones whatsoever – just a bloody awesome performance of one of Appetite For Destruction's most killer tunes.
Guns N' Roses will be headlining tonight's Firenze Rocks Festival. Wonder if they'll return the favour and bring up Dave Grohl and co. for a jam? We sure hope so…
