March 1 is St. David’s Day, the patron saint of Wales (“Cymru”). Notable people of Welsh descent include Richard Burton, poet Dylan Thomas, and me on one side of the family.
The title is a literal translation of “Long live Wales!” courtesy of an on-line English to Welsh translation service. Listen to a midi version of the Welsh national anthem (“Hen Wlad fy Nhadau”) here. A better-known piece of Welsh patriotic music is “Men of Harlech” (midi here) that is a rousing good march and also served as the tune for the alma mater of my high school. The Welsh like to sing.
