Featuring the wordless vocals of Clare Torry, whom also sang the Dolly Parton song "Love Is Like a Butterfly" as the theme music to the 1970s Wendy Craig/Geoffrey Palmer sitcom Butterflies; and later featured heavily on Culture Club's The War Song.
On Pink Floyd tours it has been replicated by the late Vicki Brown (I could feature her in this thread later); Venetta Fields; & Sam "Stop" Brown (daughter of Vicki & Joe "Picture Of You" Brown) pre & post fame on their 1987 & 1994 tours.
The seminal Let It Bleed album track features the uncredited vocals of Merry Clayton, who has sung on loads of other late 1960s and beyond tracks. The most famous being Lynyrd Skynyrd's Sweet Home Alabama.
Since, the 1970s on tour this has been the go to song where Mick Jagger would introduce a female singer with a great set of pipes to have a go at this classic.

Cat Stevens - Remember The Days Of The Old Schoolyard (1977)
The last US and UK top 40 chart hit for almost three decades for the Island folk rock singer songwriter featured an uncredited female duet vocal of pre "Pearl's A Singer" hitmaker Elkie Brooks. However, for the video she was replaced Milli Vanilli style by Linda Lewis!
The Roxy Music frontman (& his ill suited caterpillar on his top lip) pop cover of the 1962 Wilbert Harrison blues standard, later covered by Canned Heat had a memorable video featuring his then Texas "Prairie Rose" model girlfriend Jerry Hall, before she upgraded to Mick Jagger ( I guessed she never fancied being called Jerry Ferry); & is now married to the defacto ruler of the UK, USA & Australia .... media magnate Rupert Murdoch.
However, Jerry Hall's part in this video is about as true as Uncle Rupert's The S*n "News"paper coverage of 1989 Hillsborough Stadium Disaster.... the female vox was actually supplied by the late Vicki Brown.
