Killaloe, also Killaloo, was the regimental march of the disbanded UDR [Ulster Defence Regiment] and it was a cracker, the only bit of good that they did.
I had a recording of this very funny song a long time ago, I can remember just a few snatches, and as you rightly say the French-mock French dosen`1t make it easier to remember.
One part I re-call were " a boy stood up from Clare heard his mother called a me[a]re, and smacked mesere a crack between the eyes"
And," You may talk of Bonyparte, or any other party, and c`mon com parley vous, for we larned to sing it aisy, that song the marshallaisy" etc.
I recall the singer, a small be-spectacled man, and he was brilliant,
and from the Belfast area, this was on BBC Northern Ireland, around the early 70s.
Someone from around Belfast would have the words of this song. Ard Mhacha.
