Yet another dormant thread I found while searching for something. The Scottish version referred to above is by frequent contributor Jim McLean and is as follows:

THE ENGLISH ROYAL FAMILY

How many more did we have in'64 of the English Royal Family?
The queen she had four with expenses for a score of the ERF
Margaret is doing her best, trying to keep up with the rest
Did she have a little girl or boy?
Did Viscount Linley have a brother? Does it matter it's another
Of the ERF
Marina, time to change Marina

The Duke of Kent believed that his wife should conceive for the ERF
So way out in Hong Kong they increased the merry throng of the ER
And up in Scotland, here's the rub, guess who's joined the pudding club
Princess Alexa-a-a-andra
So princes, dukes and peers as well, help to increase and to swell
The ERF
Oysters, don't forget the oysters

I may have transposed a line or two from a third verse which I'm sure is in Jim's book, but I can't put my hand on it at the minute.
