For anyone interested in a wonderful place to stay or have a workshop in North Wales, I can hugely recommend the Trigonos Centre:

I did a workshop there for the University of Bangor last month, and its a stunning location in the Nantlle valley looking up to the west side of Snowdon. Sadly I didn't have an instrument but at one of the students I was working with is a harpist. We had 5 welsh speakers in the group and they were very interesting about the fact that Welsh has distinct accents and dialects in a very small geographic area. Apparently its possible to for a native speaker to tell which valley another native speaker comes from!

As an Anglo-Saxon, I do applaud the efforts of the Welsh and Scots Gaelic communities to try to keep their language going in the face of the relentless tide of English - there's something wonderful about the sound of the speech and song, even if I don't know what they are saying!
