Mike - you forgot Rhys Ifans, Ioan Gruffudd, The Superfurry Animals, the late Catatonia, Bryn Terfel, Griff Rhys Jones, Nicole Cook, Joe Calzaghe and a number whose names I can't remember at the moment.
And in case the Yanks have forgot their past I have heard that Abraham Lincoln was of Welsh decent. And so, unfortunately, was Murry the Hump. Eryl
