"Us and Them" is the seventh track from English progressive rock band Pink Floyd's 1973 album, The Dark Side of the Moon. It was written by Richard Wright and Roger Waters and sung by David Gilmour (harmonies by Wright). It is 7 minutes, 51 seconds in length, making it the longest song on the album. When performed live throughout the 70s, it was even slightly longer, though in later tours, as evidenced in bootlegs and the releases P•U•L•S•E and Delicate Sound of Thunder, it was sometimes up to a minute shorter.
