Jimmy Fallon’s Awesome Barbershop Quartet Sings R. Kelly’s ‘Ignition’ [VIDEO]

I'm glad Jimmy Fallon is bringing his popular 'Late Night' sketches and bits to 'The Tonight Show.'

I love The Ragtime Gals, the barbershop quartet. In the past they performed versions of songs you would never expect from a barbershop quartet, such as 'I Wanna Sex You Up' and 'SexyBack.' Their latest hilarious attempt, R. Kelly’s 'Ignition.'
