This simple SATB arrangement of the carol "While Shepherds Watched Their Flocks" is set to the well-beloved American folk hymn "My Shepherd Shall Supply My Need" (from Southern Harmony, 1835). Its calm, pastoral character offers a nice contrast to the upbeat Yorkshire melody to which it is usually sung.
