One of the "Folksongs popular in Ireland" pamphlets that we have has Bill Staines' "A Place in the Choir," without any attribution whatever. I think Planxty liberated Norman Blake's "Billy Grey," more or less in cold blood, retitling it "True Love Knows no Season." I don't know if they paid any royalties, but I doubt it, since he grumbled about it in introducing the song at a concert once.
