I had this song stuck in my head before I slept and when I woke up this morning and I didn't remember the lyrics just the rhythm and music

There are so in love and they look awkward but I like the song even more now. (After some research I think they are acting? Maybe they were just friends because he got married to someone else 8 year before this song)
This is a 70s gem.
