Beatles’ legend Paul McCartney has no qualms about performing with modern artists, finding time to collaborate with those like Kanye West, Brittany Howard (of The Alabama Shakes) and more over the years. The latest collaboration is one with The Killers, as Macca made an unannounced appearance with that band on New Year’s Eve.

Though it was a private concert held on St. Bart’s, there’s still something quite awesome about seeing The Killers and Paul McCartney jam out on “Helter Skelter.” A video of the sit-in emerged on The Killers’ Facebook for all to enjoy. Check it out below.
