I have it somewhere in one of the old Gwynn Publishing booklets. I'm on my way out at the moment but, if this isn't answered by time I get back, I'll seek it out. The Welsh words were by Talhaiarn (John Jones) and the music by Owain Alaw (John Owen). It was being sung by Edith Wynne in the early 1860s and was apparently a big hit in London. The tune became particularly popular and was used for other songs as well.

What about it interests you,Richard?
