Reviving this thread that I stumbled across during a search. Reproducing the lyrics posted upthread by Snuffy:

VICTORIA
(Brian Na Barbar)

The lion and the unicorn were fighting for the crown,
When up spoke Irish Cheddar1 and they both came tumbling down
The second George departed too, from Stephen's Green in town,
But they're coming down for you, Victoria!

CHORUS:
Victoria, they're coming for you soon,
Victoria, it may be when the moon
Is shining on December frosts or on the flowers of June
But they're coming down for you, Victoria!

A gas main2 burst in Belfast on the eve of Poppy Day,
And loyal doors, and windows too, blew rapidly away.
Came the dawn in Dublin, and the naughty so they say3
Sent a message from the Castle to Victoria.

Georgie lost the seat he had4; king Billy lost his head;
The lion lost his balance and5 the unicorn he fled,
And sure as you're a humpy stumpy bumpy lump of lead
They'll be coming down for you, Victoria.

Nelson's weather eye, they say, was looking out for squalls;
They're nervous in the Phoenix Park and round old Dublin's walls
But whosoever keeps his place and whosoever falls,
They've a double date with you, Victoria !!!

1. It certainly sounds like 'Irish Cheddar', but what does that mean?
2. I had always heard 'A gatling burst'. On re-listening it does 3. sound more like 'gas main', but it's impossible to be sure.
3. Who or what are 'the naughty so they say'?
4. I had always heard 'lost his seating'. Could be either
5. Sounds more like 'from' to me

No-one seemed to answer these queries at the time, and I'm interested to know if anyone can answer them today (maybe a member who joined since then will know).

(Sorry the format has got a bit screwed up by my cut/paste, please refer to Snuffy's posting higher up if necessary).
