When i was listening to old 70s songs (Harry Chapin, Gordon Lightfoot), YouTube suggested this song:
The lyrics to this song are fantastic. It's about some villagers jelly that some people who live up on a mountain have a "buried treasure" which is a rock that is inscribed with "Peace on Earth." The villagers only find this out when they go up the mountain and kill the mountain people. The villagers then turn over the rock and read what it says.
