This bonus track from the special Target edition of Unorthodox Jukebox
features a face-to-face duet with jazz singer Esperanza Spalding. Speaking with Rolling Stone
, producer Jeff Bhasker, (Fun.'s "We Are Young
") called the tune a "kooky, true-jazz classic, like 'Pennies From Heaven.' It's sounds like a song you'd hear in a club in 1920s Paris," he continued, "even though we recorded it on a laptop; we even use old microphones to give it that feel. It started with an Emile beat, and then I added a Django Reinhardt sample that I screwed with in Ableton; then Esperanza came in and nailed her bass and vocal parts live, like an old pro."
