Paul McCartney's summer tour took him to New York's Madison Square Garden last night where, during the encore, he was joined by Bruce Springsteen and Steven Van Zandt. You can check out footage of it above.

They performed "I Saw Her Standing There" and following its conclusion, McCartney called for it to be played again. Van Zandt took the solo on the first go-round, while McCartney's lead guitarist, Rusty Anderson, did the honors on the second.

"Rockin' out with The Boss--Sounded so good we had to do it twice!" McCartney posted on Instagram.

Springsteen and McCartney, who have a combined age of 143, have a unique history playing the Beatles song that begins, "Well, she was just 17." Back in 2012, McCartney sat in at Springsteen's concert in Hyde Park for it and "Twist and Shout," a night which also made headlines when, towards the end of the latter, the sound was cut off by authorities due to the fact that the show broke curfew.

McCartney is spending a bit of time in the New York area right now. He'll play the Garden again tomorrow night, which will be followed by two nights at the Barclays Center in Brooklyn later in the week and another two at the Nassau Coliseum on Long Island. He did two nights at Newark, N.J.'s Prudential Center earlier this week. The U.S. dates will conclude Oct. 1 at the Little Caesars Arena in Detroit.

For Springsteen, he's preparing for his upcoming Broadway run at the Walter Kerr Theatre, a quick ride up 8th Ave. from the Garden. Previews begin Oct. 3, with the official opening scheduled Oct. 12. It will run through Feb. 3, 2018.
