How do you celebrate your birthday if you’re Bruce Springsteen? By jumping on stage with pal Jackson Browne, apparently.

Tuesday, the day before the Boss turned 66, he attended Browne’s show at Red Bank’s Count Basie Theatre in his home state, New Jersey. Though Springsteen watched most of the performance from the crowd, he joined Browne on stage and together they performed a 12-minute version of “Take It Easy,” which Browne co-wrote with The Eagles’ Glenn Frey in 1972.

“Say hello to Bruce Springsteen,” Browne told the crowd before Springsteen came out and strapped on a guitar.

Watch fan-shot footage of some of the show:

Springsteen and Browne have worked together for decades — Springsteen even inducted Browne into the Rock and Roll Hall of Fame in 2004 — and have performed together a number of times.
