Fleetwood Mac - You Make Loving Fun - YouTube
There are very few pre-1980 songs I like. That is one of them, because it sounds like it could be from the early 80's (for a while, I didn't realize it was from the seventies). The pacing and length later became standard for pop-rock songs, the guitar-playing feels ahead of its time somehow, and singing about sex was ahead of its time for the genre.
