James Bond title songs, as a rule, have the name of the movie in the chorus. That was a bit of a challenge with On Her Majesty's Secret Service, so producers opted to go with an instrumental in the opening sequence. Hal David and Burt Bacharach were brought on board to write another song for the movie, and they brought in Louis Armstrong to sing it. The 68-year-old jazz great was sick at the time, but he nailed the song in just a single take. He died less than two years later.
