Madison Square Garden concertgoers got a surprise this past Friday (9/15) when Paul McCartney was joined on stage by a pair of Jersey rockers for the show's encore.

As Sir Paul returned to the stage to extend the show for the packed crowd, Bruce Springsteen and Steven Van Zandt showed up to share the spotlight with the Beatle.

And share the spotlight they did! They rocked out to the Beatles classic "I Saw Her Standing There".

Thankfully, one attendee, YouTuber Jim Powers, had great seats and caught a perfect video of the trio. Check it out:
