"Wearin' o' the Green" was widely adapted in America. Before the Civil War it was "Benny Haven's," (DT) a song about the tavern near West Point where cadets who later became generals or gin'rals in the Late Unpleasantness may have sung a verse or two--except for Ulysses, who was legendarily tone deaf. Then during the war the Union sang it as "Army of the Free" (DT) and the Confederates did "Wearin' o' the Gray" thereby coming full circle. That song is on Horton's "Homespun Songs of the Confederacy" tape [CD? Don't know].
