I think that's not the same Dafydd as the Saint Phil:

····· DAFYDD Y GARREG WEN -Cân werin

"Cariwch," medd Dafydd, "fy nhelyn i mi,
Ceisiaf cyn marw roi tôn arni hi.
Codwch fy nwylaw i gyrraedd y tant;
Duw a'ch bendithio fy ngweddw a'm plant!"

"Neithiwr mi glywais lais angel fel hyn:
'Dafydd, tyrd adref, a chwarae trwy'r glyn!'
Delyn fy mebyd, ffarwel i dy dant!
Duw a'ch bendithio fy ngweddw a'm plant!"

DAVID OF WHITE ROCK

Dafydd said, 'Bring me my harp, I'll try to put a tune on it before I die. Raise my hand to reach the string. God bless you my widow and my children.

Last night I heard the voice of an angel saying: 'Dafydd, come home and play through the glen!'

Harp of my childhood, farewell to your music, God bless you my widow and my children!"
