I suddenly thought that the whole thing will about statues in Belfast and Dublin which were targets for being blown up. The reference to Victoria and Poppy Day would be anachronistic otherwise.

Perhaps it's 'Georgie lost his seat he(?) - presumably a statue to one of the German Georges.

King Billy losing his head is presumably an attack on a statue of King William III.

These first two were presumably in Belfast. The pillar with the statue of Nelson was blown up in Dublin on 8 March 1966. The Go Lucky Four immediately wrote and recorded a song to the tune of the Battle Hymn of the Republic called 'Up Went Nelson', which was on the streets by 10 March. The Dubliners included a song called 'Poor Old Admiral Nelson' in their show at the Gate Theatre that same year (which they preceded with a piece of poetry by Louis MacNeice about Dublin statuary).

So from all this, I deduce that the statue of Queen Victoria in Dublin was also a target for attack, and the song was produced after the attacks on statues in Belfast.

However, this came to me in a blinding flash out of nowhere this morning, so could be entirely off beam!

Shoh slaynt,

Bobby Bob.
