OK, hint time, but I'm having trouble coming up with much of anything useful.
First, more lines, including the title:
_ ____ ___ ____
Your heart belonged to only me
But that was many tears ago
Now your love is just a memory
Yeah, yeah, yeah, yeaaaaah, yeah
This song reached the #14 position on the US charts in 1965. That same year, the artist also had a #9 hit that had to do with being born down in the boondocks.
Edit: And, for what it's worth (probably not much), an 80s cover of this song by Linda Ronstadt charted in the top 40.
