Pigs on the Wing 2

This acoustic number is probably the closest thing to a love song Floyd ever made - their lyrics veered more toward social and political commentary. The song was written by Roger Waters.

The song is split into two parts at the beginning and end of the Animals album, nesting three tracks between it. This is similar to the structure of Wish You Were Here, which featured "Shine On You Crazy Diamond" split into two parts with three tracks between.

Waters believes there's empathy in his writing for "Pigs On The Wing" parts 1 and 2. Interviewed in 1978, he said that the song was about his second wife-to-be Caroline Christie (they divorced in 1992). Decades later, Waters said its message is wider reaching. He told Mojo in 2017: "Maybe it was about someone. My feeling now is that it's more general. It's saying, if we don't care for one another and have empathy for one another, then all we're left with is this… crap." Waters added: "The final verse - 'Any fools knows, a dog needs a home, a shelter from pigs on the wing' is a nod towards the idea of safety and succor in the arms of a loved one. It's the idea that we're not alone that we have a responsibility to one another in a global society."
