The song of the South, and a definite tune that will be stuck in your head. This song was originally composed in the 1850s and became the anthem of the Confederate States of America during the American Civil War. This is composed by Daniel Decatur Emmett, or at least accredited as so.
About this version:
This version is a digitalized MuseScore copy of a 1859 digitalized print I found online. The .jpeg file appears to be very high resolution scans. The cover says, "Written and Composed expressly for Bryant's Minstrels by Dan. D. Emmitt. Arranged for the pianoforte by W. L. Hobbs."
