[1][2] A collaboration between Richard Wright and Anthony Moore, it is the only song on the album for which David Gilmour receives no writing credit.
It is the first occasion that Richard Wright provided lead vocals on a song since "Time" and "Us and Them" on the band's 1973 album The Dark Side of the Moon.
In a 1994 interview with In the Studio host Redbeard for the US premiere of the album, Wright revealed he did the vocal in the first take.
[3] According to bassist and past touring member, Guy Pratt, the song originated from his idea of a bass riff involving harmonics.
[4] This song was never performed live by Pink Floyd, although it was performed on David Gilmour's 2006 On an Island Tour, and appears on the Remember That Night DVD and on the bonus CD of the deluxe version of Live in Gdańsk.
