You may be looking for "Nelson's Farewell" which is about the sudden and explosive removal, in the wee hours of the morning, of a relic of English Imperialism in Dublin, to wit, the column and statue of Lord Nelson that was (I believe) outside the main post office. The version I have comes from The Dubliners. It begins: Now, poor old Admiral Nelson is no longer in the air, Tooral-ooral-ooral-ooral-oo. On the eighth day of March in Dublin City fair, Tooral-ooral-ooral-ooral-oo. From his stand of stones and mortar He fell crashing through the quarter Where once he stood so stiff and proud and rude. So let's sing a celebration, it's a credit to the nation. To poor old Admiral Nelson, tooraloo!
