Paul McCartney surprised fans with Beatles and Neil Young songs at surprise show

Producer Andrew Watt and Red Hot Chili Peppers drummer Chad Smith played an intimate show in The Hamptons, New York and as if watching that duo perform at a a 250-capacity venue isn't a treat enough, the crowd at Stephen Talkhouse were in for an even bigger surprise when Paul McCartney came out to perform two songs.

Dressed in jeans and a zip-up hoodie, Macca started off with a duet of Neil Young's Rockin' In The Free World with Andrew's girlfriend Charlotte Lawrence and then sang one of his own songs: I Saw Her Standing There by The Beatles. Former Hall & Oates guitarist and Saturday Night Live bandleader G. E. Smith was also onstage to round out the band.

Andrew and Paul have worked together before. Macca was featured on a track off The Rolling Stones' latest album Hackney Diamonds, which Watt produced.

Last year, Andrew also revealed he wrote a currently unreleased song with McCartney during what was supposed to be a casual meeting. “Suddenly, we had a song,” he told The New York Times at the time. “From a cup of tea to a song. Doesn’t it sound easy?”
