Mostly Irish, except when it's Scottish, which it is half the time. When it isn't green coloured blue grass. Gaelic Music would be the accurate way of taking. The term Celtic I think comes from Bretons wanting to stress their national identity. And you can't blame them for that.

But in fact, while Breton music is wonderful stuff, it's much closer to French music than to Gaelic music, (or even to Welsh, where of course there is close affinity when it comes to language).

The thing about the Wild Rover of course is that it isn't even an Irish song in origin. It was collected in Norfolk, and that's the version that the Dubliners picked up. Any good song will end up being sung in Ireland, and then people assume it's an Irish song to start with, rather than to finish with. The same goes for other Irish favourites like "I live not where I love" and "Fiddlers Green". I might start a thread on that, asking for other Irish songs that aren't.

The other thing about The Wild Rover that peoiple always miss is that formally at least, it's a Temperance Song. I strongly suspect that originally it was a seriously meant Temperance Song too.

As for DADGAD - as I said, I've nevwer got into it. But on a bouzouki ADAD is about the most popular Irish tuning, so has anyone had any success with DADADA or ADADAD?
