George IV- Couldn't Stand My Wife

(By the way, when it says George III in brackets, he only speaks that line, then it switches back to George IV)
I'm George IV, the regent king
Which means I was just standing in
Acting king because my dad
George III had gone barking mad
(George III) Banana!
Great palaces I did design
Buckingham was one of mine
Art and fashion I so rated
(George III) And wives?
That's more complicated...
Actresses and duchesses
The great loves of my life!
I loved more girls than I ate pies
But I couldn't stand my wife...
(George III) He couldn't stand his wife!
Go away
I only married Queen Caroline
When my debts began to climb
'Cause if I agreed to tie the knot
(George III) I said I'd pay off the lot!
But the wedding plans were full of strife
'Cause I already had a wife
(George III) A divorced Catholic?!
Dad did sigh, but the mad old goat just wouldn't die...
(George III) Still here! Oh, spoke to soon...
At last, I can go solo!
As true king my reign began
Though I was now older than your nan
And as the ruler of our nation
I banned my wife from my coronation
And knowing now that I did hate her
She promptly died just three weeks later
But all the pies that I got through
Meant ten years later, I died too!
(George III) Hello! Have we met? I'm a kangaroo!
Actresses and duchesses
The great loves of my life!
I loved more girls than I ate pies
But I couldn't stand my wife...
I had just ten years on the throne
Do you remember that?
No, all that you remember is...
I was really fat...
