Watch Justin Timberlake And Jimmy Fallon Perform "SexyBack" With A Barbershop Quartet

Like whoa.

[UPDATE: This video is no longer available.]

Justin Timberlake has been dominating music news for a few weeks now, and while it's obviously strategic (he has a new album coming out he has to promote!) his sense of humor and fun is making his media blitz fun to watch. JT's most recent antic: showing up on Late Night with Jimmy Fallon to perform "SexyBack" with a barbershop quartet!

While The Be Sharps will always be our favorite barbershop quartet, The Ragtime Gals are giving them a run for their money with their striped suits and straw hats!
