I have listened to many versions of this song and there are some good ones but my very favourite (by far) is by the group, Scartaglen with female singer Connie Dover. I have the LP but not sure if that particular album was ever released on a CD or not.
Really wonderful arrangements and beautiful vocals and harmonies on this great, great powerful song! Connie Dover later went on to release solo recordings. I don't think Scartaglen is still together as a band.
