That play on the familiar phrase “live and let live” is the basis of the whole song. McCartney took a saying about tolerance and turned it into something harsher, more violent, more suited to the Bond world. In another explanation of the song’s meaning, he later suggested that the song can also be heard as being about letting go, dropping problems and stress, almost as a kind of “to hell with it” response when life presses in on you. There is also the Bond dimension, the idea that when you have a job to do, you do it well and give the other fellow hell. All of these readings coexist within the song.
