I've always thought that this was written by Stan Kelly (in a pub, but you could probably say that about most Stan Kelly songs). There are now hundreds of verses, some more singable in public than others.

These are the ones Bob Webb and I sing:

I was born in Liverpool, down by the docks,
Me religion was Catholic, occupation hard knocks;
At stealin' from lorries, I was adept
And under old overcoats each night we slept.

CHORUS: In my Liverpool home,
In my Liverpool home,
We speak with an accent exceedingly rare
Meet under a statue exceedingly bare
And if you want a cathedral we've got one to spare
In my Liverpool home.

Old Sam Cunard had the ships and the means
To carry the emigrants, people with dreams;
They sailed from the Mersey their fortunes to find,
But my dad always said the best ones stayed behind.

CHORUS

'What's your religion?' a fellow once said.
So I climbed in me wellies and I kung-fu'd his head.
'Don't be angry!' he cried. 'I'm not starting a nark.
Do you worship at Anfield or Goodison Park?'

CHORUS

And when I grew up I met Bridget McCann
She said, 'you're not much but I'm needin' a man,
'Cos I want fifteen kids and a house out in Speke'.
Well the spirit was willin'
But the flesh it was weak.

CHORUS

Way back in the forties the world it went mad,
Mr Hitler threw at us everything that he had,
When the smoke and the dust had all cleared from the air
'Thank God!' said the old man,'the pier-head's still there'.

CHORUS

- close to the Spinners' version but with a verse or two we found elsewhere

BTW The 'exceedingly bare' statue stands outside Lewis's department store in Liverpool. It's very...er... detailed.
