Gareth - Dylan Thomas said 'Praise the Lord we are a Musical Nation', not 'Thank the Lord...' Sounds much better, you'll agree. And if you are suggesting that the name 'Caerdydd' is a recent invention, this is not so. It occurs in the 12th century 'Book of Llandaf' (as 'Caer Di' and 'Caer Dif' - which gave the Anglicised form 'Cardiff'). In the 14th. century it is to be seen in a poem by Dafydd ap Gwilym. Regards!
