Citando:
""I always saw those [songs] as the equivalent of writing a James Bond film theme," McCartney explained in Barry Miles' biography, Many Years From Now. "It was a challenge. It was something out of the ordinary for us because we actually had to write in a key for Ringo and you had to be a little tongue in cheek." Like school kids, the songwriting partners procrastinated on the assignment until the last possible moment. Starr's track would be the last one composed for the album."
