"I suspect it is related to the above posting from Nigel.

I would be interested if anyone knows more."

Down to Petticoat Lane to hear the people talk.
A fellow was selling birds; he had a remarkable stock.
I gave the fellow half a crown and he gave me his ...
CHO Cock-a-Doodle Doo. It's nothing to do with you.
It's a very small cock, but it's all that I've got
And it's nothing to do with you.

I put it under my coat and I began to walk.
I hadn't got very far when it began to squawk.
A lady was passing by and she gave me a hell of a shock:

Before I got there that dozzy old hen had bitten a lump off my ...CHO

And now my song is done I can no longer stay.
No point in staying here. I must be on my way.
Just one more thing to ask before I take a walk.
Is there any young woman in the room who would like to handle my ...CHO
