Hi - me again -

Just did a spot of googling, and I think the Foster version IS what you're looking for. Website http://www.magpiemusic.com/schoolguide.html sez:

BATTLE CRY OF FREEDOM
MAGPIE's program of music from the Civil War era, like their other programs, goes beyond just the story of the war, of the government and the armies, to tell the personal stories of the people of the times and how they dealt with the crisis gripping the nation. The program begins with music from the abolitionist movement and from the Underground Railroad, music borne, as was the war itself, from the malevolent institution of slavery. Many claim that the Civil War was fought not over slavery but over "states' rights"; but the preeminent "states' right" in dispute was undoubtedly slavery. The songs deal with Mary Brown, wife of the famed raider of Harper's Ferry, John Brown, and with the dangerous flight of the fugitive slaves to freedom in the north. They also celebrate the great conductor of the Underground Railroad, Harriet Tubman. From there the program tells the story in song of the soldiers and the loved ones they left behind. The songs are some of the well-known tunes of the day, which described the hardships of army life and of the war itself, as well as the difficulties faced by those "keeping the home fires burning." The songs also express the patriotic fervor that motivated both sides in the conflict. Then the program winds down with songs expressing everyone's weariness with the war, with the exception of one "unreconstructed" rebel, and the hope that these hard times would come again no more in the words of famed songwriter, Stephen Foster.
