What is up with this song?

http://youtu.be/G1a4UqgN53w    Since I'm a computer idiot I can't quite figure out how to attach this link, but maybe it can copied and pasted? It's an old version of Rhinestone Cowboy, by Glenn Campbell, complete with lyrics.  I feel it's only fair to warn you that once you listen to this song it will be embedded in your brain. For days on end.  Possibly forever. I have Glenn Campbell's Grammy award show performance to thank for doing this to me. I thought that if I watched it on Youtube and really belted out the lyrics that it might help exorcise it from my brain. I was wrong. It's now stronger than ever. I've even got Jonathan singing it. We've been possessed by this song. I fear we shall both go mad. Now that I know the lyrics I can't believe that it was such a hit in its day. They're awful. And Glenn's hair in the video is equally as disturbing.  I might need shock therapy. Or very strong medication. Or both.
