The chords in this are really interesting. They start out as the normal 1950s chords, but then there are some weird modulations. I thought a particular one was interesting: The song is in C major, but halfway through the verses, there's an E major (with a G# accidental). The lyric for that part is "Yeah, I know she's gonna treat you wrong," which that accidental note seems to help convey.
