Man, I'm so glad I don't watch tons of movies like some people. For a lot of these songs, one of the first things mentioned, if not the first thing mentioned, is that you can't hear the song without thinking of some movie or TV show. That's so sad. I always think of the music, the song, where I was when I first heard it, the people I was with, what I was doing at the time.
The Byrds are the 60's. A simpler time, a time when you could take a passage from The Bible, set it to music, and have a hit on the radio. The words are simple and inspiring, and have a ring of truth that everyone feels when they hear them. To have a beautiful song like this inextricably associated with something as mundane as a movie is just sad.
