This song by the late Andrew Gold may not be as appreciated as I think it deserves because of its use as a sitcom theme song. But for several years, Gold, who formerly played on a bunch of Linda Ronstadt tracks, had a string of worthy top-40 singles. I appreciated his craftsmanship as a composer and arranger.
This song is one of a whole group of songs about friendship that I love. Apart from salvation itself, friendship is one of God's greatest gifts. And some friendships are life-changing, blessings beyond full expression.
