I second that suggestion, Martin Ryan; I rely on html code every time. It is tedious with many keystrokes, but it has never failed me yet.

Without a doubt, other threads on the topic have spelled out the conundrum of the question; repetition it may be, but I will feel easier in my conscience by an obvious response to the title question.

That is, the specific question, Who wrote the English translation which is sung to this traditional Irish tune?

And here is the dilemma: an O'Connor performed the recording that made the tune notorious; and an O'Connor wrote the English words. Naturally, they are two different O'Connors. So there is some validity to credits, in copyrighted published music, which mentions "O'Connor" without telling you which O'Connor it is!

Obviously Sinead O'Connor performed, and did not write, the English words. But it gets confusing to people because the translator's name, Frank O'Connor, is too similar to the performer's.

In one of my "after the Irish" volumes of English translation at home, possibly An Duanaire or possibly Gregory Stephens, I know the Frank O'Connor English version is presented. I will go look it up (not at home presently) and will report back to this thread in a future post.
