Johnny Cash...The Ballad of Ira Hayes
Johnny Cash recorded this song in 1964, long before Clint Eastwood made his movies about Iwo Jima. I don't remember it, but then music, while endorsed as a cultural good by my parents, was not a big part of our lives.
It's very weird how artists can make a statement in an extremely popular show, but it gets over-ridden, ignored, shouted down and trampled by the chatter boxes that provide much of our political discourse.
