Jimmy Fallon has been keeping us extremely entertained with his few couple days as the latest host for the The Tonight Show. Yesterday evening, he hit the stage with a barbershop quartet for a rather unique performance of the classic remix to R. Kelly's song 'Ignition'. This rendition definitely had to make The King Of R&B himself proud. Hey Jimmy, we're gonna need a studio version of this track ASAP. Watch this performance above.
