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.
It is not a marching song. It is not necessarily defiant. It is a promise: We shall overcome someday. Deep in my heart, I do believe.. It has been a civil rights song for 50 years now, heard not just in the U.S. but in North Korea, in Beirut, in Tiananmen Square, in South Africa's Soweto Township. But We Shall Overcome began as a folk song, a work song.
