Swing Low Sweet Chariot is one of the best known African American spirituals/hymns, reaching back into the 19th century and still sung today. It can be played either as a slow, plaintive hymn or done faster in a more jazzy/bluegrass style if desired. More info about the history of the song can be found in the Wiki article here.
