After yesterday’s news that Axl Rose would be fronting AC/DC for a number of scheduled tour dates, the classic rock universes merged ever closer at Coachella last night. With Guns N’ Roses headlining the festival, the band brought out none other than AC/DC guitarist Angus Young to help add some rock and roll to the party.

With Angus Young on hand, the band broke into two early AC/DC classics that were staples of GNR’s live show: “Whole Lotta Rosie” and “Riff Raff.” You can watch fan-shot video of the sit-in below:

The show also featured a cover of The Who’s “The Seeker” and loads of GNR classics, like “Paradise City,” “Patience,” “Sweet Child O’ Mine” and more. Check out the setlist below:
