LOS ANGELES, Jan 29 ― Jimmy Fallon continues to dazzle us with his musical capabilities and this time he roped Natalie Portman and pop star Sia to join him.

Donning a bunch of black-and-blond Sia-inspired wigs, Fallon and the Tonight Show’s house band The Roots together with Portman and Sia performed a lively rendition of the classic, oft-covered song Iko Iko.

Sia led the singalong, with Fallon on the spoons and Portman banging wood blocks while the rest of the band played an eclectic array of instruments.  

The Dixie Cups’ Iko Iko is perhaps best known for its use in the 1988 movie Rain Man.
