Sia Debuts Her Cover Of “Unforgettable”

The movie Finding Dory—a long-awaited sequel to Finding Nemo—arrives this summer, and new music from Sia is slated to soundtrack the end credits. She performed her string-slathered version of "Unforgettable" this week on Ellen. Nat King Cole's version of the song may be the most famous; it has also been covered by Dinah Washington, Aretha Franklin, Marvin Gaye, Lou Rawls, and many, many more.

Finding Dory hits theaters on June 17.
