"Pigs (Three Different Ones)" is a song from Pink Floyd's 1977 album Animals. In the album's three parts, "Dogs", "Pigs" and "Sheep", pigs represent the people whom Roger Waters considers to be at the top of the social ladder, the ones with wealth and power; they also manipulate the rest of society and encourage them to be viciously competitive and cut-throat, so the pigs can remain powerful. Summary The song's three verses each present a different "pig". According to Waters, the first verse's "pig man" refers to businessmen in general, whereas the second verse refers to conservative politician Margaret Thatcher, leader of the opposition at that time. The third verse clearly identifies its subject as being morality campaigner Mary Whitehouse, who is described as a "house proud town mouse" who has to "keep it all on the inside." In 1992, on the Westwood One radio special Pink Floyd: The 25th Anniversary Special, Roger Waters told Jim Ladd that the "Whitehouse" mentioned had nothing to do with the home of the U.S. president, the White House, after Ladd told Waters he interpreted the last verse as referring to Gerald Ford, who was US president at the time the song was recorded (although the verse also includes Whitehouse's first name). Halfway through the song, David Gilmour uses a Heil talk box on the guitar solo to mimic the sound of pigs. This is the first use of a talk box by Pink Floyd. Gilmour also plays a fretless bass guitar, with a pick, doing two short, syncopated bass solos—one before the first verse, another before the third. When the final verse ends and a guitar solo emerges, the bass line moves into a driving eighth note rhythm, sliding up and down the E minor scale in octaves, beneath the chords of E minor and C major seventh. Roger Waters, usually the band's bassist, played a rhythm guitar track on the song instead. The song was released as a promotional single in Brazil, albeit in an edited form of only four minutes and five seconds in length. On some cassette tape versions of Animals, the song was divided into two parts after the first verse, fading out on side one and fading back in on side two, in order to minimize the total length of tape. Live versions The normal length of the song performed live was roughly 17 minutes (some would top
