This psychedelic track was one of three songs produced by Adele collaborator Paul Epworth for New
. The producer's approach echoed the three experimental, improvised Fireman
albums McCartney has made with former member of Killing Joke, Martin "Youth" Glover. McCartney told The Sun
the song's back story. "It comes from a story in my mind," he said. "I had this thought, almost like an old black and white movie, about a holocaust kind of thing."
"To begin with, I didn't have any words. So what I would do in that Fireman/Epworth process, is to block out the words by singing nonsense."
"And I'd hear myself say," added McCartney, "'The night!' OK, so that's good, I've got a word. Then you gradually block in all the words."
