I am presently working on a new web site and you can find the words to the St Day Carol in both English and Cornish plus hear a recording made by Cornish scholl children at the following URL. I'm afraid the Cornish of the children is not very clear as they only had a short time in rehersal.

There are other Cornish carols on the site and more will be added shortly. It may take time to download first time so please be patient.
