There is a patriotic song called “Beasts of England” which is used to memorialize Animalism. Most revolutions and movements have some kind of anthem, because people can use it to feel camaraderie and momentum. The song begins by prophesizing good times to come.
Beasts of England, beasts of Ireland,
Beasts of every land and clime,
Hearken to my joyful tidings
Of the golden future time. (Ch 1)
The song is first used to rouse the animals and to incite a revolution. It gives them a common cause: to overthrow the “Tyrant Man” and take back the fruits of their labors. The song is used after the revolution whenever they have an event memorializing it.
However, Napoleon retires the song because he sees it as a threat, and he does not want the animals to get antsy and remember how they once rebelled against oppression, since he became the oppressor.
