No, no, they all sang Rosselsongs.
Leadfingers' suggestion of Procreation is a good follow-up:

When mad king George was dying and the throne of Britain was at stake
Six royal dukes set to with zeal to spawn an heir for Britain's sake
Five royal dukes proved impotent, the victor was the duke of Kent
The duke alas his arrow fired, his duty done, soon expired
But not before, hurrah, hurrah, he'd fathered queen Victoria and saved us from the foreigner.

Procreation, procreation, there's one thing we're good at, it's procreation
Traditionally we spend our time perpetuating the royal line
Procreation, procreation, there's nothing so royal as procreation.

(Leon Rosselson)

There are two more verses but you can buy the book.
