Credit: MJ KimBeatles legend Paul McCartney got a little help from his friends, Taylor Swift and Jimmy Fallon at the Saturday Night Live after-party on Saturday night.

McCartney joined the 25-year old pop star and The Tonight Show host for a rave up of the Fab Four’s rock and roll rave up, “I Saw Her Standing There” and played backup to Swift for her hit, “Shake It Off.”

Video of the performance has surfaced on TMZ.

The party followed the live broadcast of SNL‘s 40th Anniversary Festivities, which included McCartney’s solo performance of “Maybe I’m Amazed” coupled with a duet of “I’ve Just Seen a Face” with Paul Simon.

McCartney’s performance was proceeded by a cheeky introduction courtesy of Keith Richards, who joked, “In the early Sixties a band came out of England and it changed the world. But enough about the Rolling Stones: Ladies and gentlemen, Paul McCartney.”

Other performances included Miley Cyrus paying tribute to Simon with a cover of “50 Ways to Leave Your Lover,” with Simon rounding out the broadcast with a rendition of “Still Crazy After All These Years.”
