Here's a version I rewrote a couple of years ago (and posted on the Cat), reflecting the way we seem to have got more foxes in towns these days:

Old Daddy Town Fox

Old Daddy Fox went out one night,
He crossed the road to a town so bright,
He spied a bin and he laughed with delight,
"I'm glad that I came to this town oh, town oh, town oh,
He spied a bin and he laughed with delight,
"I'm glad that I came to this town oh.

He opened the bin and he searched around,
And a tasty curry he quickly found,
And a half-of a chicken weighed a couple of pounds,
"Oh this is a mighty fine town oh..."

Old Mother Flipper Flopper climbed out of bed,
And out of the window she stuck her head,
Crying "John, John, there's a fox to be fed,
The fox who's come to the town oh."

So John came down and he opened up a tin,
And he gave him the meat that was within,
Saying "We can't have our Foxie a-getting too thin -
He's the best fox in this town oh."

Daddy Fox went home with a bag full of grub,
"Therell be some for the wife, there'll be some for the cub,
Then I think I'll go out for a stroll down the pub –
Yes, for sure it's a mighty fine town oh."

Old Daddy Fox and his cubs and his wife,
Ate up that food without any strife,
And they never had such a supper in their life,
And the little ones chewed on the bones oh.

Now Old Daddy Fox he lives in his den
It's under the holly bush back of number ten,
"Oh we're never going to go back to the country again,
It's a far better life in the town oh."
