After spending my entire life living in New York, a city that is known for having a HUGE Irish population, I fail to see the need for them to re write Ireland.
I mean in the original version of the song (the one on the CD) it's clear that the Ireland being sung is Paulette's twisted and false version of what Ireland is like and that her fantasy is what keeps her going day after day. Keep in mind that it is just her fantasy and we as the audience know that she most likely never left Cambridge Massachusetts before.
