“The Boss” is back, baby!

Following a peptic ulcer disease diagnosis, the “Born To Run” singer had to postpone a string of performances last year. In September, he announced he would be taking time off to recover. But now, the rock phenom is finally back in action.

On Tuesday, Springsteen, 74, and the E Street Band played at the Footprint Center in Phoenix, opening with a “Good evening, Arizona” to the crowd, followed by the crowd-stirring “Lonesome Day.” His 29-song performance proved to be a “triumphant reboot” for the iconic musician, who showed no signs of his past ailment during the three-hour show, according to the Associated Press.

Aside from “Born in the U.S.A.,” Springsteen performed signature hits like “Rosalita,” “No Surrender,” “Glory Days” and “Dancing In The Dark,” while adding a few covers to the mix. According to ABC News, the heralded rocker played “Nightshift” by the Commodores and a surprising rendition of “Twist and Shout” by the Isley Brothers.

“Phoenix, first I want to apologize if there was any discomfort because we had to move the show last time ... I hope we didn’t inconvenience you too much,” Springsteen, who postponed nearly 30 shows on his world tour last year, said before closing out the show.

Springsteen’s Phoenix date marked the first stop on his 2024 world tour. Before ending in Vancouver, British Columbia, on Nov. 22, he and the E Street Band will play in 17 countries across 52 dates.
