Unfortunately the quality of the Kennedy recordings, despite being the only commercially available of Mona Douglas's singing, leave much to be desired. I would recommend either of the following cassettes as being of better quality recordings of the song in quaestion.
GOW ARRANE - 16 Traditional Manx Gaelic Songs performed unaccompanied by various solo artists.
MANNIN VEG VEEN - Arraneyn as Kiaulleeagh Tradishoonagh Ellan Vannin (Traditional Music & Songs of the Isle of Man) by Brian Stowell & George Broderick.
Both of those cassettes should be available from The Manx Museum, Douglas, Isle of Man.
