Love this video - excellent illustration of the power of a good choir over an audience.
I heard them in London before they auditioned.,

Cymraeg :
Mae hen wlad fy nhadau yn annwyl i mi
Gwlad beirdd a chantorion enwogion o fri

Tros ryddid collasant eu gwaed.

Gwlad Gwlad,
Pleidiol wyf i'm gwlad,
Tra mor yn fur i'r bur hoff bau

English:
Land of my Fathers, O land of the free,

Her brave warriors, patriots much blessed,

I am devoted to my country.
So long as the sea is a wall to this fair beautiful land,
May the ancient language remain.
