"Last Night I Had the Strangest Dream" written by (I think) Ed McCurdy.

Yesss!

AND...
"Christmas in the Trenches" by John McCutcheon
"Peace is..." by Fred Small
"Let The Band Play Dixie" by Bob Gibson
"The Universal Soldier" by Buffy Saint Marie
"Where Have All The Flowers Gone?" by "Unca" Pete Seeger
"And The Band Played 'Waltzing Matilda'" by Eric Bogle

Or maybe some of these are "anti-war" as opposed to "pro peace??" Does the distinction matter, Azoic??
