I did an intense study of the Civil War for 3 years straight, with 2 additional years of passing interest. I love the songs. "All Quiet Along The Potomac" is one great song. Other good ones are:
Who Will Care For Mother Now?
Wrap The Flag Around Me, Boys
We Are Coming, Father Abram
Cheer Boys Cheer
Grafted Into The Army
The Rose of Alabama
Stonewall Jackson's Way
Lilly Dale

Just some ones I pulled off the top o' my head.
