My favourite version is by an Irish folk singer by the name of
Anne Byrne. Anne had a beautiful voice (reminds me of early Joan Baez type voice). Unfortunately, all of her albums, including the one with her singing, "Come By The Hills" was only released on LPs.
She had several albums but none ever released on CD.

Anne's version of, "Come By The Hills" is gorgeous! Most of her albums were released in the 1960's. There is a few videos of Anne Byrne singing on Youtube but not this song.
