Morticia, the song is "Santa Baby" and it was one of the songs I thought about when I saw this thread. And Walrus, I have that same association with the song--the execution of Private Slovick (perhaps not his name in the movie), with the camera in a helicopter pulling away from the battle weary soldiers who have been forced to become a firing squad as they take aim at the deserter...an unforgettable scene. The third one is the Tom Lehrer:

"Hark the Herald Tribune sings, advertising wondrous things..." and "Let those raucous sleigh-bells jingle, hail our dear old friend Kris Kringle, driving his reindeer across the sky...don't stand underneath as they fly by."
