"You Only Live Twice", performed by Nancy Sinatra, is the theme song to the 1967 James Bond film of the same name. Music was composed and produced by veteran James Bond composer John Barry, with lyrics by Leslie Bricusse. The song is widely recognized for its striking opening bars, featuring a simple 2-bar theme in the high octaves of the violins and lush harmonies from French horns. It is considered by some to be among the best James Bond theme songs, and has become one of Nancy Sinatra's best known hits. Shortly after Barry's production, Sinatra's producer Lee Hazlewood released a more guitar-based single version.
