St David's Day

Just to remind everyone that today is St David's Day; though I can't remember of what or of where he's the patron saint.  I have vague recollections of Max Boyce and Druids in golden wellies, and a most satisfying and historic victory the last time England played at Cardiff Arms Park.  Perhaps opera buff Del Boy can remind us -- though I'm not sure if Del isn't himself a fraud.  What kind of opera buff has no opinion on which version ofTommy (surely the greatest opera of them all) is the greatest -- Live at Leeds or Live at the Isle of Wight?
