Instead of a Song, boys, I'll give you a Toast,—
Here's the memory of those on the twelfth that we lost:
That we lost, did I say? nay, by heav'n, that we found,
For their fame it shall last while the world goes round.
The next in succession, I'll give you the King,
Whoe'er would betray him, on high may he swing!
And here's the grand fabric, our free Constitution,
As built on the base of the great Revolution;
And longer with Politics, not to be cramm'd,
Be Anarchy curs'd, and be Tyranny damn'd;
And who would to Liberty e'er prove disloyal,
May his son be a hangman, and he his first trial!
