R. Kelly’s 2003 R&B anthem “Ignition (Remix)” is probably considered “old school” by now, but Jimmy Fallon made it “old, old, old school.” The late night host remixed the remix by taking it back to the golden years of the 1930’s by doing a barbershop quartet version. Jimmy and his a cappella all-stars, the Ragtime Gals “toot tooted” and “beep beeped” their way to another fantastic moment.
