Well, the music by married couples, or bands including married couples, theme has pretty much run its course. I'm down to couples who weren't happily married and got divorced long ago, and/or whose music I'm not that crazy about. I'm afraid I never liked Fleetwood Mac a great deal, at least in their most commercially successful period. They were very capable (great rhythm section), and I didn't actively dislike them, but hearing their songs a few times on the radio was enough.
But I always thought this song was a killer. It's almost cheating a bit to use it, because the married couple were the bass player, John McVie, and the keyboard player, Christine McVie, and this song features other people--another couple, actually, Lindsey Buckingham and Stevie Nicks, but I don't think they were ever married. But I like it a whole lot better than some of their bigger hits, e.g. "Don't Stop Thinking About Tomorrow". Yuck. I never did care for it, and then when the Clintons used it as their inaugural theme song, my view of both was confirmed: bland '70s pop for establishment liberals.
This track has got a real edge, though. Love the drums in the verses.
