I think I have it sorted out:

THE ROSE AND SHAMROCK
(William J. Allen)

I love my native country and I am not to blame
And there should be no reason why you should not do the same,
The Englishman loves England and true friendship combined,
When Englishmen and Irishmen, their hands and hearts will join.
 

Chorus:
When the Rose and the Shamrock in love are entwined
And England and Ireland in friendship combined,
Then we can show when our flag is unfurl'd,
That England and Ireland can face all the world.
 

The Russian Bear is growling, but we heed not his growls,
And if they are not careful, they'll soon be turn'd to howls,
With a million men in fighting don't make us feel afraid
While we've our Connaught rangers and the gallant Ninth Brigade
 

When bold Napoleon Bonaparte the world to conquer tried,
He went well on 'till Pat and John, at attacked side by side
With Wellington up on the land, and Nelson on the sea;
This mighty man they conquer'd and Great Britain still was free
