In the digital age, emerging musicians often rise to fame by busking on the streets and reaching audiences through YouTube. It’s rare, however, to see global rock icons return to street performances — but U2 did just that during their appearance on The Tonight Show Starring Jimmy Fallon.

Fallon is known for orchestrating spontaneous, off‑the‑cuff moments with his guests. So when U2 visited the show, he dressed the band in elaborate disguises and stationed them undercover at New York’s 42nd Street subway platform. Unbeknownst to commuters, a hidden camera inside Fallon’s sunglasses—humorously dubbed the “U2cam”—captured the entire undercover busking act.

Before launching into live music, Fallon, donning his own mayor‑of‑Manhattan garb, announced the “native New Yorkers” as local street performers available to entertain at weddings, parties, or bar mitzvahs. The scene was set—and no one suspected the legends were about to play themselves into oblivion.

The set began with the iconic “I Still Haven’t Found What I’m Looking For.” For the first minute, passersby paid little attention—mall‑rats in motion. But Bono’s look-in‑the‑raw vocals inevitably began to draw a small crowd . After gauging the crowd, Fallon whispered, “Plan B,” revealed the band’s identity, and the assembled crowd erupted in cheers—on their way home from work, New Yorkers didn’t expect a surprise concert in the subway.

The show closed with an intimate, unplugged rendition of “Desire,” with The Edge joining in as clapping and sing‑along erupted—a once‑in‑a‑lifetime treat for commuters.
