In the second night of Justin Timberlake's artist-in-residence week at "Late Night with Jimmy Fallon," he joined an impressively-arranged barbershop performance of his own 2006 smash hit "SexyBack."

Performing as part of Fallon's "Ragtime Gals" (which includes one of our faves, New York comedian Tom Shillue) Timberlake showed off his range with the delightfully retro version of the song. Obviously, "the harmony of a barbershop quartet and the music of Justin Timberlake" is a match made in heaven. Check out the clip above.
