Jimmy Fallon And The Backstreet Boys Redo “The Thong Song”

Jimmy Fallon brought back his barbershop quartet The Ragtime Gals for a performance on Tuesday’s Tonight Show.

The gals happened to be The Backstreet Boys.

What followed was a stirring rendition of Sisqo’s The Thong Song.

The Backstreet Boys were also on the show to promote their extended DNA tour.
