Given the following context:  In 1975, Pink Floyd bought a three-storey group of church halls at 35 Britannia Row in Islington and began converting the building into a recording studio and storage space. In 1976, they recorded their tenth album, Animals, in their newly finished 24-track studio. The concept of Animals originated with Waters, loosely based on George Orwell's political fable, Animal Farm. The album's lyrics described different classes of society as dogs, pigs, and sheep. Hipgnosis received credit for the packaging of Animals; however, Waters designed the final concept, choosing an image of the ageing Battersea Power Station, over which they superimposed an image of a pig.The division of royalties was a source of conflict between band members, who earned royalties on a per-song basis. Although Gilmour was largely responsible for "Dogs", which took up almost the entire first side of the album, he received less than Waters, who contributed the much shorter two-part "Pigs on the Wing". Wright commented: "It was partly my fault because I didn't push my material ... but Dave did have something to offer, and only managed to get a couple of things on there." Mason recalled: "Roger was in full flow with the ideas, but he was really keeping Dave down, and frustrating him deliberately." Gilmour, distracted by the birth of his first child, contributed little else toward the album. Similarly, neither Mason nor Wright contributed much toward Animals; Wright had marital problems, and his relationship with Waters was also suffering. Animals is the first Pink Floyd album that does not include a writing credit for Wright, who commented: "Animals ... wasn't a fun record to make ... this was when Roger really started to believe that he was the sole writer for the band ... that it was only because of him that [we] were still going ... when he started to develop his ego trips, the person he would have his conflicts with would be me."Released in January 1977, the album peaked on the UK chart at number two, and the US chart at number three.
