Can You Name this Carol?

This is the first installment of the All New Name That Carol Contest. All clues are taken from Stories Behind the Best-Loved Songs of Christmas by Ace Collins (thank you Susan Tuten for the book!).

• This carol came from the fields of the South, born from the inspiration of a slave's Christmas
• While most Negro spirituals centered on earthly pain and suffering with only heaven offering joy and happiness, this song embraced the wonder of lowly shepherds touched by God on the first Christmas
• This carol was first taken to the world in the 1880's by the Fisk Jubilee Singers
• At that time, it was compared to two other Civil War songs, "We'll March Around Jerusalem" and "Tramp, Tramp, Tramp the Boys are Marching"
• I have one more clue that will totally give it away but I'm saving it for a desparation move.
