Who knows what will happen when a Russian billionaire throws a private New Year's Eve party on an island?

At his mansion home on St. Barts, wealthy Russian businessman Roman Abramovich held a New Year's Bash for the ages, featuring private concert sets from Guns N' Roses, the Rolling Stones, and the Killers, who brought up a special guest in former Beatle (and Stern Show guest) Paul McCartney.

The 74-year-old musician joined the Las Vegas-based rock band on stage to perform the Beatles' "White Album" screamer "Helter Skelter," with Sir Paul—the song's writer and original singer—trading lines with the Killers' frontman Brandon Flowers.

The Killers posted the video on their Facebook page. "So far, so good," the band said of 2017.
