If you were anywhere near Grand Central Terminal in New York on Monday, you might have bumped into Bono and the rest of U2.

The band showed up at the subway stop to sing Angel of Harlem.

It was documented by fans on social media.

It is all apparently for U2's upcoming Friday night appearance on Jimmy Fallon's Tonight Show. The band was supposed to play a weeklong residency in November but had to cancel because of Bono's bike crash.

On Sunday, the singer and the host were spotted filming a skit spoofing the accident. Spoiler alert!

The band's world tour starts in Vancouver on May 14.
