I guess it should be me who answers, having been mentioned in dispatches, and all.

The Myrddin ap Dafydd lyrics are only about 20 years old. I'll have to look around for other lyrics, but there should be a number. Many will be in the 'bardd gwlad' category - unattributable and difficult to date, but I'll see what I can find.

In actual fact, Welsh folk songs differ from English (and presumably others) in that the 'tradition' is rather like a game: you have a body of music, and you have a body of words, and the artist then decides which verses to sing to which tunes. Of course, with the 'Mentra Gwen' measure, you can only sing it to a suitable tune.

Anyway, that's what the 'canu penillion' tradition is in Wales.

Now - the reason I contributed to earlier threads is because a friend of mine is writing a history of Welsh folk music and she asked me to dig up the dirt on the early English tunes. When she's done, that bit ought to interest you!

Strangely enough, I had it in my mind to do research very similar to yours! But ... you go right ahead but let me have a read when you're done, OK?

So: what is it you want? Words, or tunes?
