The Diegetic James Bond: Goldfinger (1964)

The only source music in Goldfinger is heard during the pre-credits sequence set in an unnamed Latin American country. After Bond plants explosives in a drug lab hidden in an empty oil tank, he saunters into a club where a woman is dancing to music that sounds vaguely Latin but is more likely a John Barry pastiche of some indeterminate Latin style. The accompaniment, both onscreen and on the playback, is provided by guitar, stand-up bass and tambourine or other percussion.
