Heard a stunner of a song at Shewsbury Folk Festival, which was announced as traditional. Can you identify this simple and very moving song. The idea is that two men go off to war, "one wore ???, one wore blue"; "one is ?????, one is kind(?)" but the cannonball that hits one doesn't care about that. The final(?) verse is, "Two girls waiting by the railroad track, one wore blue and one wore black". The refrain throughout is "All on a beautiful morning".
