Mar 01, 2007 — The Welsh are celebrating St. David's Day today, in one way or another. St. David, or Dewi Sant, as he's known in the Welsh language, is the patron saint of Wales. Todd Moe talks with Hefina Phillips, president of the Ontario Welsh Festival, about St. David and next month's festival in Kingston. She says David was a sixth century Celtic bishop who spread Christianity among the pagan tribes of western Britain.
