Civil War: Songs of the North collects 15 Union-centric instrumental ballads like  Weeping Sad and Lonely/When This Cruel War Is Over, When Johnny Comes Marching Home, and The Battle Cry of Freedom, all of which are impeccably performed by Nashville-based multi-instrumentalist Craig Duncan and a small army of talented session musicians.
In the years since the Civil War, The Battle Hymn of the Republic has been used frequently as an American patriotic song. The song was one of Winston Churchill's favorite hymns, and was played at his state funeral in St Paul's Cathedral in 1965.
