The beasts at the other farms started singing Beasts of England after receiving word of rebellion from Napoleon and Snowball. Pilkington and Frederick began to fear that their animals would also rebel.

It describes to you how the animals are going to take over England.

Answer the question

Napoleon bans "Beasts of England" because the song is about freedom and rebellion and so Napoleon does not want them to rebel
