Working Man - the Welsh version

I have listened to the version by Rita MacNeil, but she uses different lyrics in the second verse from the Welsh version I heard recently.
The Welsh version I heard was something like:
"At the age of 16 years years,
My father (through or maybe in?) his tears..."
The rest of the lyrics were words to the effect of the father not wanting his son to "go down underground" - very moving!

Does anyone have lyrics to the Welsh version?
Thanks!

Hi guys!
Just found these 2 versions, Rita’s and David Alexander’s, who sings what I call the “Welsh version”!
Being Welsh, I am deeply moved by David’s version!

Hope you all enjoy them (both!) as much as I do!
