Sorry Ladyjean
Your ref:

"Incidentally, the proper name for "Danny Boy" is "The Londonderry Air". Londonderry is in Northern Ireland, so it was very appropriate."

That is exactly what is inapprpriate, Londonderry is what London call Derry, it is in Northern Ireland, which is why it should be called Derry (which by the way is an angicised version of the Irish 'Doire')

Maybe I give away too much of my sentiments - If the blue clicky link above doesn't work try these address's ;
