"Dixie's Land" was the basis for numerous parodies by soldiers, North and South. "Union Dixie" was one such parody. While it used Emmett's music, the author of the lyrics is anonymous. It was one of many unsuccessful Northern attempts to 'recapture' the song which, even today, is associated with the Confederacy.
It was recorded by Tennessee Ernie Ford on Tennessee Ernie Ford Sings Civil War Songs of the North.
