In this film, Barry introduced the percussive theme "007"—action music that came to be considered the "secondary James Bond theme". He composed it to have a lighter, enthusiastic and more adventurous theme to relax the audience. The arrangement appears twice on the soundtrack album; the second version, entitled "007 Takes the Lektor", is the one used during the gunfight at the Gypsy camp and also during Bond's theft of the Lektor decoding machine. The completed film features a holdover from the Monty Norman-supervised "Dr. No" music; the post-rocket-launch music from "Dr. No" is played in "From Russia with Love" during the helicopter and speedboat attacks.
