Back to Urchnoc chéin mhic cáinte....

Anybody know where I could find the Tab (music). I want to learn it for the whistle

Try getting a hold of two great little books by Seán Og and Mánus O Baoill, entitled "Ceolta Gaeil 1 & 2. ( They have been long awaited by the like os myself!) They have loads of lovely songs in the Irish language. They are published by Ossian, I'm sure you can contact them on "www. Ossian.com" .
Urchnoc chéin mhic cáinte is definitely in one of the volumes, I'm not sure which one though.
Hope this helps,
Seosaimhín
