Natalie Portman [1] stopped by The Tonight Show on Wednesday night to talk up her new movie, Jane Got a Gun. In addition to her interview — in which she admitted that she has yet to see Star Wars: The Force Awakens [2] — the actress teamed up with Jimmy Fallon [3], The Roots, and Sia to perform a version of the classic Mardi Gras anthem "Iko Iko" with color-coordinated instruments (and all donning Sia's infamous two-toned wigs). Watch the video above now, then check out all the other times Jimmy nailed it with his classroom instruments [4].
