Don't know if I'm remembering this correctly but how about the arrangement of WALTZING MATILDA in the SciFi (or was it "Future History") flick "On The Beach"??? As I remember it had a plaintive quality that grew and permeated then replaced the sound of the Jolly Swagman as he and his "Matilda" danced of into the Out back in the "Never Again" dreamtime.   Ooooo! Heady stuff.
