Yo, Angun, sorry I didn't get back to you on the 'Oslo crowd' subject; I've been up to my eyes here and haven't hardly had a spare minute. Magpie might be able to help you out.

However. The version I posted was adapted by Clannad and became over the years their 'signature tune' prior to the 'Harry's Game' days. If you can get your hands on the live in Switzerland album - Clannad in Concert, 1978 - you will be up there on the floor boppin' with everybody else.
The version above is slow and 'with soul' mar a dheá, and has a different melody line from the spirited 'in your face' version from Clannad. And Seán Bán lived barely a km from the Ó Bhraonáins and the Dúgans

It's called 'The Folk Tradition', I think.
Hope you get to Ireland this summer. Go West young man!!!
