I heard a song at Starbucks a couple of years ago that's bugging me. It's from the mid 1960s or so. Two female singers in harmony. I think it may have been in triple time.
The hook in the chorus is the most memorable: "Ay, ay, ay!" sung in three long notes, outlining a minor chord going upward. (A, C, E if you're in A minor.)
Any ideas?
