Final answer:
In George Orwell's 'Animal Farm,' 'Beasts of England' is banned by the pigs in power to suppress revolutionary sentiment and replaced with a non-inspiring song that supports their regime.
Step-by-step explanation:
The song "Beasts of England" is banned in George Orwell's novel Animal Farm as a revolutionary song that represented the hopes and dreams of the animals for a better life without human oppression. Once the pigs, who take charge of the farm, consolidate their power, the song is considered subversive and potentially threatening to their control. It is replaced by a new song, "Animal Farm, Animal Farm," which lacks the inspiring message of the old song and serves to reinforce the pigs' new regime and their revised principles.
