Bump for those links. I have to admit, it's fascinating to see the Welsh language in writing. And to hear it spoken, it's such a lovely and lyrical language.
Speaking of things Welsh, let's give a nod to Dylan Thomas, and "How Green Was My Valley".
Also recommended is "Hedd Wynn". You can get a copy from Sain Recordiau. I paid an extra 5 pounds to have my copy converted from PAL to NTSC. The audio on my copy is Welsh with English subtitles if you have trouble following it. All English audio versions are available too. Hedd Wynn is the bardic name of a young Welsh farmer who sought to win the chair awarded at the national competition for poets. He was conscripted into the Royal Army and ended up sending his submission from the battlefield in France. I won't spoil the ending for those who wish to watch the movie.
