That is strange. I remember singing that in my primary school playground in about 1969/70. Only remember singing the first lines though....the "Are you ready for a war,we are the english" and "Yes we're ready for a war for we are the irish" part.

Haven't thought about it since then and have no idea where we learnt it from. It was a Roman Catholic school in London and most of us had Irish parents. I imagine the teaching staff dissuaded us from singing it.
