I'm not familiar with the song, although I've known the title ever since seeing it on the back of a Skillet Lickers album thirty years ago or so. However, a while back I heard on internet radio an old recording (1920s?) of a harmonica player doing a "hunting" son which occasionally used that phrase, "run, N*gger, run" (apologies to those who are offended by asterisks) - but "N*gger" (apologies) was clearly the name of a dog. FWIW.
