 Roger Waters used inflatable pigs at many shows on his 2006–2007 tour "The Dark Side of the Moon Live", specifically, when he performed the song "Sheep", concluding the first part of the show.The pigs used on tour were decorated with slogans and pieces of song lyrics, and with various drawings.During select performances at open-air venues the pig was released to "fly" away, a reference to the idiom "Pigs might fly".
