I just saw this post on a harp email group I belong to - don't think he'll mind if I quote his message:

Happy St. Piran's Day to you all. For those of
you unfamiliar with this saint, he is the patron of
tin miners and the patron saint of Cornwall. For more
information see

http://www.st-piran.com/st-piran.htm

An appropriate way to celebrate would be

(1) to eat a Cornish Pasty

(2) to look at Charles Winpenny's wonderful daily
photos of Cornwall

(3) to explore Cornish music at

www.an-daras.com

lots of Cornish tunes with midi files, etc.

(4) to play Cornish tunes on the harp.
