After checking the newspaper article, I'm inclined to think I must have read it, or one very like it, a couple of years ago, from which I copied the text. If the tune was only composed then and there, as the article claims, it's hard to see how it could have come from Norway, as the Wikipedia account suggests. Despite Swansea's origins as a Viking port, it seems unlikely that it would retain such close cultural ties with Scandinavia into the 19th/20th Century. But I could be wrong…
