Let me see that thong ….

The Backstreet Boys and Jimmy Fallon made a classic out of Sisqo’s “Thong Song” Tuesday, February 11, 2020, on “The Tonight Show.”

On top of that, the boys did an acapella version of a Shai song that they used to sing at the beginning of their career, with Howie taking over those vocals and showing the world that they can sing a song like that twenty years later without any practice.
