Sia, Natalie Portman, And Jimmy Fallon Sing "Iko Iko" Just For The Hell Of It

true story!

Jimmy Fallon will do just about anything to get you to watch his videos, and here's proof. In a new video, one whose origins we have no interest in knowing so as not to spoil its wonderful randomness, the Tonight Show host is joined by The Roots, Sia, and for that extra touch of virality, Natalie Portman (what?), for a rousing rendition of "Iko Iko," that classic New Orleans song popularized by girl group The Dixie Cups in the mid '60s. Everyone's wearing Sia wigs (where can we get one of those?), people are playing spoons, cups, buckets, everything. In fact, here's the full instrument list is:

Sia - vocals
Jimmy - spoons
Natalie - blocks
Questlove - kick drum, wood block
Kamal - conga drums
Frank Knuckles - plastic paint bucket
Mark Kelley - cups
Tuba Gooding Jr. - guiro
James Poyser - deck of cards
Captain Kirk - cue ball & 8 ball
Black Thought - maracas
