Back to Abby's posting of 7 Aug '01, the 'Traditional' South Welsh version quoted from Brinley Richards "The Songs of Wales" goes on to a second verse which Abby hasn't posted. (Lucky me, I just picked up an 1879 re-print of the book for £3-99 at my local OXFAM shop. They had a second copy with the last dozen pages ripped out!)

Verse 2

Buom unwaith yn gariadon,
"Hob y deri dando,"
Ti a geisiaist dori'm calon,
Dyna ganu eto;
Am fynudyn pwy fu'n hidio?
Druan am dy dro,
Deri dando wyt ti'n gwrando?


Nigel
Hen gân co,
Canig hen y co,
Hob y deri dan y to.

Verse 2 (English words by Walter Maynard same source)
And as oft I sigh and say, love,
"Hob y deri dando,"
I ask why thou dost delay, love,
"Hob y deri dando,"
Can it be thou heedest not If we ne'er meet again?
Am I then so soon forgot?
Do I love in vain?
All night and day I sigh and pray for thee, sweet Jane.
