Found a reference to the song being sung at a funeral (a favorite of the deceased) at Monasterevin, Kildare. So could be Irish. The title is "The Blacksmith." The site is listed as www.irishmusicmail.com, but the message is that it is no longer there.

Someone was looking for it last year at another website, and posted the same words that Sorcha posted above- (same last two lines missing).
