It took me a while to find the song Dick suggested. Here is a link. It's called "Ballad of October 16" on a CD Smithsonian Folkways came out with in 1996 called That's Why We're Marching: World War II and the American Folk Song Movement. It's an interesting collection of songs, and the Almanac Singers are well-represented. The songs trace the change in attitude of the folk singers, from pacifism to supporting the war.
