After making a huge splash on SNL over the weekend, Justin Timberlake’s residency on Late Night with Jimmy Fallon has only upped the funny!

Timberlake took to the stage Tuesday night with Fallon and barbershop quartet, The Ragtime Gals, in tow for a rendition of his now classic “SexyBack.” He later performed his song “Mirrors” from his upcoming album, The 20/20 Experience. The barbershop quartet’s harmonies are flawless and even got the audience clapping along to the beat. The remix is worth a listen, a share, and maybe even a sing-along.
