Maroon 5 and Jimmy Fallon disguised themselves as bearded buskers and hit the New York City subways in a charming Tonight Show web video. Singer Adam Levine and guitarist James Valentine performed acoustic renditions of the group's 2014 hit "Sugar" and Queen's 1979 hit "Crazy Little Thing Called Love," with the late-night host assisting on tambourine.
During the Queen cover, most people walked by the performance disinterested – and totally oblivious to the musicians' true identities. (It also helped that Levine also masked his signature vocal style with a huskier, heavier tone.) But the subway supergroup ended the ruse after that song, launching into a low-key version of "Sugar." Fallon added chipmunk-falsetto backing vocals throughout the track, as the crowd, filming the random scene on cell phones, quickly closed in.
