On last night's "Late Night with Jimmy Fallon," The Lonely Island turned in a rare live performance by staging an elaborate version of their single "YOLO," warning of the dangers that lurk around all corners of everyday life.
They were backed up by Fallon's house band The Roots, which made the performance even more awesome, of course. Stepping in for Adam Levine, who sang the chorus of the original song, was Fallon himself, and The Roots frontman Black Thought delivered his own rapped verse to replace Kendrick Lamar.
All around, pretty ambitious. Check it out above.
