Harold W; will you please quote your source? Mine is Len Graham's notes for 4CC46 published 1987 and the copyright of the songs and arrangements are claimed by Cranagh Music on that date.

Len Graham and Padraigín Ní Uallacháin have done very considerable work in returning songs to traditional circulation, often remaking them from fragments or incoherent versions. They have received far too little credit because people assume that their performances are reproductions of traditional songs. This is not so - each song is the subject of careful reconstruction.
