“Hey guys, I’m in the 50th street subway station right below Rockefeller Center with Bad Bunny,” Fallon, 50, told viewers as he and Bad Bunny disguised themselves. “Now the two of us are about to go on the subway platform and start busking in disguise.”

Bad Bunny then launched into a performance of his own song "NUEVAYoL," with Fallon accompanying him on the tambourine. Videos of the performance taken by passersby spread on social media before the full sketch aired on "The Tonight Show."
