"Good Old Mountain Dew" (ROUD 18669), sometimes called simply "Mountain Dew" or "Real Old Mountain Dew", is an Appalachian folk song composed by Bascom Lamar Lunsford and Scotty Wiseman. There are two versions of the lyrics, a 1928 version written by Lunsford and a 1935 adaptation by Wiseman. Both versions of the song are about moonshine. The 1935 version has been widely covered and has entered into the folk tradition becoming a standard.
