A big thanks to eifion for the translation!
Wake up sleepy welsh, land of song.
Deep is the weakness,
Small is the flame,
The harvest is cruel, but the tune is beautious
With the song of the lonely swan in my chest.
(this bit in english)
Every day, when i wake up
I thank the lord i'm welsh.
I discovered the true paradise of rhyl.
A feast of graves excited a shy welsh woman
