Jimmy Fallon, Sia, Natalie Portman and the Roots Sing "Iko Iko"

Not sure why this exists, but it's cool!

Liam Mathews

On Wednesday's Tonight Show, Jimmy Fallon, Sia, Natalie Portman, and the Roots performed a version of the much-covered New Orleans classic "Iko Iko" for apparently no other reason than it's awesome.

Natalie Portman seems confused. Questlove shreds on the woodblock. And if you're wondering if Sia wears a wig that covers her face and a giant bow on top...of course she does. She sure can sing, though. Everyone wears wigs, one half white, one half black. The color scheme is based on dominos.

Why? Because!
