On the old main road from Dublin to Cork, just north of the town of Fermoy (in North County Cork) there's an old army encampment (once British Army, now Irish) at a place called Kilworth. Just outside the main entrance is an enormous roadhouse/pub called The Glocca Morra Inn. My guess is that it was once a whorehouse! I'm not sure whether the name is genuinely local or came from the song. I'll check.

BTW, there is also, nearby, (or certainly was when last I travelled that road) the ruin of what looks to have been a much smaller pub/inn, long since fallen in. It may well have been that one was used by officers and the other by other ranks. Just a speculation.
