I hear the first verse a little differently than you. What do you think?
Our ancient sons in story were all great men they say;
But we in future glory may join as well as they.
For our noble fathers' valiant sons have conquered manys the foe.
We will loud in fame their names proclaim who fought at Waterloo.
And a couple other minor differences:
And Napoleon like a bantam cock sat mounted upon a bar
(although I don't understand what being "mounted upon a bar" means)
On a high platform there he did stand, 'twas loudly that he crew
and I think you have it correct with "'tis straight to Paris" and "wrought" (being the archaic past tense of work).
Thanks for all your transcribing work (and skill).
