OK, back to the 50's: This '54 Pat Ballard composition was recorded by The Chordettes and hit #1 that same year. The chord progression follows the "circle of fifths" for 6 chords in a row! Covered in '78 by Emmylou, Dolly and Linda for "Trio". In '81 Emmylou re-released it as a single with her doing all 3 parts because of contract disputes with the other two. Also covered by Chet Atkins and The Supremes.
Yesterday's answer: "Tonight You Belong to Me". http://www.youtube.com/watch?v=AI8NuFAETMQ A classic - probably my favorite scene from "The Jerk".
