In the last demonstration of this week we reveal* that Nature is never absent, even in the city. And if hens aren't enough, and friendly dogs, we also have horses and pigeons in the song. A decade later, I still say 'I'd give pigeons to hear from you,' as if it's a real English expression.
*We use this term in the specialised sense that Garth Crooks once used it when he 'revealed' to Sven-Goran Eriksson that England had qualified for the next round of a major championship when probably S-G Eriksson probably was aware of that, because it's the sort of thing that even a moderately successful England manager would keep himself abreast of.
