About the collaboration, Nick Littlemore said, "This is a dream record for us. We've had the idea of a vowels-based song way back before we met Elton, but it never came together until now. It turns out it was worth the wait. And in great style we finally present a collaboration with Empire of the Sun! A voice like no other, let it lead you to the dancefloor."

Luke Steele said "This song is about not letting the garden of Eden within us all be corrupted by the world."
