Amidst rumors of an impending album release, U2 have made their return to the stage. The Irish quartet made a surprise appearance during Sean Penn’s third annual Help Haiti benefit in Los Angeles on Saturday (January 11).

U2 didn’t play any new songs from their supposed upcoming album, but rather stuck to some classic crowd favorites. The three-song set consisted of “I Will Follow” from their 1980 debut album, followed by “Desire,” and “Vertigo.”

Bono and The Edge also performed with Haitian singer Anaelle Jean-Pierre earlier in the evening. The event, which was held at the Montage Hotel in Beverly Hills, had Bono remarking: “It's been a while since we played a hotel lounge, I think the last time was a bar mitzvah,” according to The Hollywood Reporter.

The benefit raised almost $6 million, according to Billboard. The new U2 album is rumored to be scheduled for an April 2014 release. It was mainly recorded at Electric Lady Studios in New York with producer Danger Mouse.
