Why should the devil have all the good music?

Unfair question, you say. And you are right. The devil does not have all the good music. (This was a song title from long ago. By Larry Norman.) 

Still, there is a huge amount of great music which is being lost as time marches on. Many excellent works in the praise and worship category. Can you believe that the 70's occurred about 40+ years ago?!? 

Let's try to recover some of the great things from the past. We can also link to audio and video. And post the lyrics, too. And the chords, too. What song would you add?
