This track was produced by Paul Epworth, who was responsible for Adele's Skyfall theme song
. It was the first tune that McCartney recorded for his New
album. He told The Sun
: "I must give Paul Epworth credit for that because he had an idea of how we could kick things off. He just said, 'I was thinking something kind of punkey.' I realized he meant something rocking, up tempo and in your face."
"So we started there and then," continued McCartney, "building up the track. I put some more chords into it, some lyrics. It turned into a real statement of intent."
