> we would not change the words of a song to suit political correctness, the song is "Traditional" and would only be performed by us in it's original form.

Then why sing it at all? If you're only doing it for fun, the alteration of one word would make no difference.

The point isn't whether the line was offensive to Irish Christians 100 years ago, it's whether it's offensive to a general audience in the modern world - and why you don't care.

Also, please explain what you mean by "political correctness," In this case, we're talking about simple respect for your presumably unbigoted audience.

Are you careful never to change even a single word in any of the trad songs you perform?
