The Lonely Island "YOLO!" (live on 'Fallon') (ft. Jimmy Fallon & the Roots)
The studio version of the Lonely Island's "YOLO!" features Kendrick Lamar and Adam Levine. Last night (July 25), however, those guest spots were filled by Jimmy Fallon and the Roots when the comedy rap band swung by Late Night with Jimmy Fallon for a surprise performance.

This is far more elaborate than your average talk-show gig, since the performance utilized the whole studio, along with a wide array of props — including everything from meat skewers to a guy in a strait jacket to a makeshift metal bunker — to illustrate the comedically cautionary lyrics.

The song comes from this year's The Wack Album.
