Bald Eagle, That would be the one I've heard - which is tremendous. First heard it sung by the late David Parry (of Friends Of Fiddlers Green fame). It for me was the definitive version. Roy Bailey came and was describing it and was taken aback by the vigour of the chorus. I seem to recall him mentioning something like "Oh, you know it". Another point in the back of my mind is that this song was featured in some play in England about the empty hay carts rolling home, though my memory may be playing me tricks.
