Yeah Yeah Yeahs frontwoman Karen O performed "The Moon Song", her Oscar-nominated track from Spike Jonze's film Her, during the 86th Academy Awards. She was joined on acoustic guitar by Vampire Weekend's Ezra Koenig, who sat next to her on stage in front of a giant moon. Ezra wore red socks that matched Karen O's dress. (Karen O, meanwhile, removed her heels for the performance.) Watch below.
