The sleevenotes specify the source. You might quote the details in order to save people who would like to help you from wasting time unnecessarily. On the offchance that the original notes aren't given with the cd reissue:

"Collected from Mrs John Currie (Peigi Nill) of North Glendale in 1932 by Margaret Fay Shaw, and published by her in ... Folksongs and Folklore of South Uist (Routledge & Kegan Paul, London 1955)."
