I suspect that "The Ball of Ballynore" is much the same song as "The Gathering of the Clans/Ball of Inverness/Ball of Kirriemuir" ("Swing your balls to your partner; and yer arse against the wall; if ye cannae get laid at Kirriemuir; ye cannae get laid at all"Unforunately many of this rather explicit song are (to) frequently sung in students/soldiers setting, and thus get more explicit by the day.
I tend to prefer bawdy songs without four-letter words - have a look at i.e "The German Clockwinder". Amazingly Robert Burns wrote a great number of, what must have been, very daring songs, i.e "9 inches will pleasa a lady..."
