The provided article text does not contain any substantive content about the origins of "Whiskey in the Jar" — it consists only of website navigation elements (menu items and an unrelated "Cover Story | Yard Act" tag) rather than the actual article body. As a result, there is no factual information available to summarise regarding who wrote the song or its history.

No details, dates, names or context relating to the song's authorship could be extracted from the supplied text, as the page content appears to have failed to load properly. A proper summary would require the actual article text from the source page.
