"Pigs (Three Different Ones)" by Pink Floyd is inspired by George Orwell's Animal Farm, which is an allegory of the Russian Revolution and the misuse of political power.
The song is part of Pink Floyd's album Animals (1977), which criticizes capitalism instead of Stalinism as it happens in Animal Farm, and it uses pigs to refer to the wealthy people with corrupted souls that manipulate society to work for them in order to gain more power and money than what they already have. The pigs in the song, which represent rulers at the top of the social structure and the government, behave in an immoral way for personal gain. The lyrics even make a special reference to Mary Whitehouse, who opposed to social liberalism and mainstream media. In the song, she is described as a "house proud town mouse".
