One English version of Hen Wlad Fy Nhadau is
The land of my fathers is dear to me,
Country of poets and singers, celebrities indeed:
Its warring defenders, so gallant and brave,
For freedom their life’s blood they gave
Land!, Land!, Pledge-ful I am to my country!
While seas secure
This land so pure,
O may our old language endure.
O land of the mountains, the bard’s paradise,
Whose precipice, valleys are fair to my eyes,
Green murmuring forest, far echoing flood
Fire the fancy and quicken the blood
For tho’ the fierce foeman has ravaged your realm,
The old speech of Wales he cannot o’erwhelm,
Our passionate poets to silence command,
Nor banish the harp from your strand
I must admit as a non-speaking Welsh language Wrexhamite Welshman I have been embarrassed on numerous occasions at the Racecourse when the Welsh language version has been attempted. I guess if sung in English then it would be equally as embarrassing.
