"Southrons, Hear Your Country Call You," Lyrics Albert Pike, music J. F. Viereck, opus 562. A few notes only are changed from "Dixie's Land."
Several sets of lyrics were composed to "Dixie's Land," and met with varying success. One that was reprinted several times was "Awake in Dixie." The original "Dixie's Land" continued to be used by many southerners in spite of its northern composer; it was the one that survived to be sung, at least by southerners around 50-75 years ago.
Neither "Southrons, Hear Your Country Call You" (1861) nor "Awake in Dixie" (1862) seem to be in the DT.

Uncle Jaque, people don't realize the low level of literacy and the prevalence of "degraded" dialect of one kind or another among both whites and blacks at the time of the Civil War, particularly outside of the urban environment. PC seems to be severely distorting our knowledge of the past and how people thought at the time.
