I 'think' this may be the final version:

Some friends & I in a public house,
Were playing dominoes the other night
When into the pub some characters came,
In monochrome (that's black & white)
"What's up" said I "who are you?"
"Who are these folk? I had to ask it.
There was Andy, Teddy & Looby Loo
Snuggling in their basket.

"Oh" said the landlord, never you mind,
I think tonight will sure suit you.
Refresh your pints, soon you will find,
That it's the Toytown annual do! ...
   
       Chorus:
And .. There .. was .. Pugh, Pugh, Barney McGrew, Cuthbert, Dibble & Grubb.
Oh how sinful, Having a skinful,
Right in the middle of our pub.
Over there was a smelly little bear,
Somebody said "That's pooh!"
And we all got blue-blind, string-tangled drunk,
At the Toytown annual do.

Then into the pub came the Tracey boys,
And Parker, with Lady P in chains.
They each bought a round of eight real ales,
But they all started drinking Brains'!
The drinking reached such a fever pitch,
That when Mr Plod came on the scene.
Barney McGrew called out for Hugh,
And painted Camberwick Green, and … there … was ...

      Chorus:

The "Riverbank" crew were sat in a corner
Quietly drinking on their own.
Ratty & Mole had a pint of "Badger's",
Badger said, "Buy your own!"
There in a smock, stood 'Windy' Miller
They say "He's a patron of the arts"
They call him "Windy" 'cos his party piece
Is setting light to his farts .. and .. there .. was ..

      Chorus:

Into the pub to shelter from the rain
Came the soldier boys of Pippin Fort
With 15 grams of good cocaine
They call their leader Captain Snort.
Stood by the bar were Popeye & Olive
Bluto offered her a fag.
Said she "No thanks, I'll roll my own,
It's true, I'd rather have a 'shag'!

      Chorus:

The animals there included Rupert The Bear,
Sean The Sheep & Lamb Chop too.
From PontyPandy, Sam Tân said;
"I think I fancy ewe!"
The 'mouse organ' played its multiple pipes
As a soggy cloth cat came in view
Professor Yaffle said "No stereotypes"
Welsh racism will not do!

      Chorus:
