The song is in my repertoire. Just occasionally folk songs open doors. I once had occasion to ring, in my English accent, The Royal Mint to try to get some information. I was answered by a frosty voiced woman with a strong Welsh accent who told me something to the effect that I would need to submit a written request in triplicate on handmade paper, signed using the blood of a virgin and countersigned by the Pope. And that I would have to send it to Llantrisant which she would spell for me since I had probably never heard of it. I said there was no need to spell it since I was aware that Llantrisant Hill was where William Price had cremated his son. Instantly she became the most helpful person in the Universe.
