Dear Liland,

My wife and I spent the best part (and I mean that in every sense) of the last year and a half in Cornwall doing primary research on a book. In the course of our travels, we ran across a bookstore in Helston, Cornwall that specializes in all things related to the Cornish tongue. They have dictionaries, histories, books of poetry and I shouldn't be surprised if they have music as well.

We have recently returned to the States and have just finished moving house and are still "in boxes", but as soon as I can lay hands on it, I'll post the contact information for the bookstore here on the forum.

Good luck in the meanwhile!
