And the Furey's do have a songbook which includes the dots to this song. It is called "The Fureys & Davey Arthur Song book". It is a Soodlum's book. Another source for the tune is THE LOW WHISTLE BOOK by Steafan Hannigan & David Ledsam. This is a tutorial for the low whistles and is very good. It has the music for this song in it. You might try Elderly Instruments for either of these items. They are at www.elderly.com. They have a search engine on their site.

All the best,

Mick
