For me, it was The Sniper Was a Woman from the TLD soundtrack. Classic Barry, his last score and IMHO one of his best. This is Sneaky Bond music at its best as Bond and Saunders struggle to get Koskov across the frontier. Barry’s cue really heightens the suspense.
Damn, now I really want to watch that sequence again. One of the best interpretations of Fleming material from page to screen.
