Some songs about the US Civil War (1861-5), these were (at the time) favourites of mine, long before I became interested in the history of the Civil War.
Paper Lace - from 1974. I always associate with a holiday we had that Easter in Pontins Holiday Camp, Brean Sands (near Weston super Mare).
Rolf Harris - from 1969. The record was a Christmas present - along with an antique telescope. I always believed it was about the American Civil War, though some say that the song, written in 1902 may have its roots a century before that.
As a youngster, I also found this a rousing hymn.
