I quite like Shane McGowan's version:

AND, I'm glad to hear it's so popular in Ireland, but it is of Scottish origin:
The earliest known printed version was as a broadside in the 1770s and it first appeared in book form in Scots Songs by Herd.[1] An early version is sometimes attributed to Sir Alex Boswell. The text is doubtless older than its 1770 appearance in broadside, as it was recorded in the Skene Manuscript, a collection of Scottish airs written at various dates between 1615 and 1635.[3] It was known at least as early as 1605, when a portion of the first stanza was written in a farewell letter, as a poem now known as "Armstrong's Goodnight", by one of the Border Reivers executed that year for the murder in 1600 of Sir John Carmichael, Warden of the Scottish West March.[4] (Wikipedia)
