U2 kicked off an eight-night run of their Innocence + Experience tour at New York City’s Madison Square Garden on July 18, and since then, highlights have included guest appearances from Lady Gaga, The Roots and Jimmy Fallon.

At their Monday night show, U2 continued to deliver by performing “Two Hearts Beat As One” for the first time in 26 years. The track hails from the group’s 1983 album War and was last performed in its entirety at the Dublin stop on U2’s Lovetown tour in 1989. “Ya happy?” frontman Bono asked the MSG crowd after belting “Two Hearts Beat As One.”

With two shows remaining in New York this Thursday and Friday, who knows which other surprise guests and forgotten favorites U2 will bring to the stage. Check out the performance.
