"AMERICAN TRILOGY" A 1971 song medley arranged by country composer Mickey Newbury and popularized by Elvis Presley, who included it as a showstopper in his concert routines. The medley uses three 19th-century songs: "Dixie" — a popular folk song about the southern United States. "The Battle Hymn of the Republic" — a marching hymn of the Union Army during the American Civil War; and "All My Trials" — a Bahamian lullaby related to African American spirituals and widely used by folk music revivalis
