You know that 50s or 60s sounding guitar song (don't know if there are any lyrics) that you hear sometimes, mostly in movies to establish a 50s atmosphere or an old diner scene or something (I think maybe it was played in Pulp Fiction during the scene where Travolta and Thurman are at that club/restaurant)? It's just three chords played every couple of measures or so, kinda slowly, with the third chord played on the downbeat and held for a while until the next chord. I can play it in my head, but I can't figure out what the chords are on my guitar, and it's driving me nuts. Anyone know what song I'm talking about?
