"Marching ON Pretoria", the Zonophone 78 rpm, mentioned above is actually an update of an 1865 American Civil War marching song "Marching Through Georgia" by Henry Clay Work. You can listen to the original American version at the Cylinder Preservation and Digitization Project of the University of California. (Thanks to Bruce Kearnan for leading me here.) Linking there from this message though results in my comment not being posted so check out the links at the flatinternational website with a search for "Marching On Pretoria" or "Zonophone".
