I found it on the webpage of Donal O'Shaughnessy via www.irishsongs.com.
I cannot however find a recording of it by him. There is a reference to Clannad and perhaps unfortunately to Francie Mooney. The Irish version is also on the above site.
At the bottom of the words is the following.
From: "Brian hOireachtaigh"
There is a contact email for Donal on the site who appears to be in New York.
Hope this helps
