I don't have any chords or music but Kate and Anna McGarrigle did three songs on the CD Songs of the Civil War that was a companion piece to the Ken Burns series on PBS. They were 'Was my Brother in the Battle?", "Better Times are Coming" and "Hard Times" The last two are Stephen Foster songs and I believe "Better Times Are Coming" was one of the last he wrote. I'll have to look for their stuff. That's all I've seen of theirs. Kindest reguards, NEil
