A horse is a horse and a man is a man
And neither can be the other
And each can survive but is much better
In the company of one another.
And while a horse is a horse and that is true
A horse is but a beast
As a cow is a cow, some ask how
On its flesh we should not feast?
For they do so in France as in other places
And I don't know how they can
For while a horse is a horse and is only a horse
It is less a cow than it is a man!
