Jackie, I never learned to speak Gaelic, my father spoke it but not fluently. You have to hear it to appreciate it....like so many languages, the written word loses something when it hits the page.
There is a popular group from Cape Breton, Nova Scotia - The Rankin Family - they have a song - a lullaby that they perform in Gaelic and it doesn't matter that you can't understand the words - you get the feeling simply from the pronounciation. It is a pity that such a beautiful language is slowly dying. I guess it is a sign of the times...many of the traditions in this area are lost to time.
I haven't read the book you refer to but I'll hunt around and see what I can find.
In the meantime, I'll see what I can do to score some verses for spring.
