Music in Protest - Vietnam and WWI

Today in class the Vietnam group presented their perilous times project on civil rights, and much of their presentation was focused on rallies and peaceful protests. This got me thinking, how else, do people protest and raise awareness about wars? Which brigns us to what I want to talk about...music. There are alot of songs out right now protesting the War on Terror, but one of my favorite songs is by Billy Joel, and it is called Goodnight Saigon. It was released in 1983, after the war, but still got people thinking about the mistakes of the past, and that is a start. The fact that it wasn't released during the war doesn't matter all that much, it raised public awareness about the horrors of the war, and educated many on the subject. In 8th grade, we had a school wide presentation on Vietnam, delivered by an ex- Washburne teacher who called in airstrikes in Vietnam for the US Air Force. He played this song for us, and it really struck me, I went home and looked up the song and researched the war  for a bit. The main point he made is that Vietnam is a war that is sometimes forgotten (we barely touched on it in our 8th grade U.S history class), and that one day there will be no veterans left. He said that there were only 3 World War I veterans left alive at the time, and that one day that would be the case for Vietnam vets. I guess what I'm trying to say is that music can be very moving and effective in anti-war efforts and education, when done well. Another very good song by The Dropkick Murphys, is called The Green Fields of France. The line that strikes me in this song is, " It all happened again, and again, and again." I think the point that The Dropkick Murphys are trying to make is that war is preventable, and we can prevent it, we just have to learn from the past. Also see Sting's Russians, which is a grim reminder of what could have been (nuclear armageadon), and also makes the point that we need to learn from the past, or maybe one day the fears of the Cold War era might become a devestating reality. "There's no such thing as a winnable war" is  a line that strikes a chord with me, and it is really true, and it is something that more people should realize.
- Please watch these three videos, the music combined with the pictures is very moving and thoughtful.
-What lines strike you in these songs? Are there any other good songs like these?
