The In the Flesh Tour, also known as the Animals Tour, was a concert tour by the English rock band Pink Floyd in support of their 1977 album Animals. It was divided in two legs: one in Europe and another in North America. The tour featured large inflatable puppets, as well as a pyrotechnic "waterfall", and one of the biggest and most elaborate stages to date, including umbrella-like canopies that would rise from the stage to protect the band from the elements.

"Pigs on the Wing" is a two-part song by English rock band Pink Floyd from their 1977 concept album Animals, opening and closing the album. According to various interviews, it was written by Roger Waters as a declaration of love to his new wife Carolyne Christie. The song is significantly different from the other three songs on the album, "Dogs," "Pigs" and "Sheep," in that the other songs are dark, whereas this one is lighter-themed, as well as also being much shorter in duration, with each part at under a minute and a half while the others are all at least 10 minutes in length.
