We don't want to fight yet by Jingo!

From The Boys of '98 by Dale L. Walker. Origins of the word Jingoist. Speaking of the friendship between Theodore Roosevelt and Alfred Thayer Mahan, naval historian.

Their friendship and mutual admiration was the product of their bellicose nationalism and patriotism. They were brother jingos, in the purest sense of that felicitous word coined in a London music hall ditty composed during the Crimean War.

We don't want to fight yet by Jingo!
if we do
We've got the ships, we've got the men,
and got the money, too!
