The Tonight Show has a unique spin on Sir Mix-a-Lot.
During the show's week of episodes in Orlando, Fla., Jimmy Fallon's Ragtime Gals performed a barbershop quartet version of Sir Mix-a-Lot's "Baby Got Back" to loud cheers from the audience.
Starting with the PG introduction of "Oh my golly, Becky," Fallon kicked off the song while dressed in his multi-colored costumes with his fellow singers, A.D. Miles, Tom Shillue and Chris Tartaro. Miles, head writer for The Tonight Show, recently announced his plans to leave the show in order to get back to narrative writing and acting.
Fallon only broke into laughter a few times during the song, first when the singers got a bit off track during the lyric, "even white boys got to shout, baby got back."
The Ragtime Gals have performed several times on the show, being joined by celebrities including Sting and Kevin Spacey, performing songs ranging from "Roxanne" to "I Wanna Sex You Up."
