I have music for Bruach na Carraige Báine in "Cuisle an Cheoil", a government publication for an Roinn Oideachais (Dept of Education)published in Dublin 1976. Hanny, if you can't find this book - with over 50 Irish language songs with notation - or another book containing the song - contact me for a photocopy: comhfhreagras@hotmail.com
A good source for Irish language recordings and songbooks is: Cló Iar-Chonachta
also, did you try the links I gave at the top of this thread (17 May)?
