 The music for the opening scene is a calypso version of the nursery rhyme "Three Blind Mice," with new lyrics to reflect the intentions of the three assassins hired by Dr. No.Other notable songs in the film are the song "Jump Up," played in the background, and the traditional Jamaican calypso "Under the Mango Tree," famously sung by Diana Coupland (then Norman's wife), the singing voice of Honey Ryder, as she walked out of the ocean on Crab Key.Byron Lee & the Dragonaires appeared in the film and performed some of the music on the later soundtrack album.
