When U2 performed their third show of a five-show run at Chicago’s United Center on Sunday, they pulled out a live rarity. Until this weekend, the band hadn’t performed their song “Gloria” in 10 years.

Although Bono introduces the song by saying they hadn’t played it in about 20 years, the band actually did perform it in 2005 on their Vertigo tour.

Check out footage below.

U2 are currently on their Innocence + Experience world tour. Check out a behind-the-scenes look at the tour and The Edge’s epic fall off the stage, here.
