This is one of a few Pink Floyd songs to use a female vocal. Alan Parsons
, who produced the album, brought in a singer he knew of named Clare Torry. Parsons explained in Rolling Stone
, March 12, 2003: "She had to be told not to sing any words: when she first started, she was doing 'Oh yeah baby' and all that kind of stuff, so she had to be restrained on that. But there was no real direction - she just had to feel it."
David Gilmour stated in Mojo
, March 1998: "We'd been thinking Madeleine Bell or Doris Troy and we couldn't believe it when this housewifely white woman walked in. But when she opened her mouth, well, she wasn't too quick at finessing what we wanted, but out came that orgasmic sound we know and love."
