Singer-songwriter Karen O will, for the first time, perform the Oscar-nominated original song "The Moon Song" for a global television audience on the 86th Annual Academy Awards, show producers Craig Zadan and Neil Meron announced today. The Oscars, hosted by Ellen DeGeneres, will air on Sunday, March 2, live on ABC. We also have a behind-the-scenes featurette which includes a message from Karen O about how the song was created.

Karen O has performed on numerous other soundtracks, including those for Frankenweenie, The Girl with the Dragon Tattoo and I'm Not There.
