The Rolling Stones share unheard version of 'Brown Sugar' featuring Eric Clapton

The version was recorded at a party for Keith Richards in 1970

The Rolling Stones have released a previously unheard recording of their hit song “Brown Sugar” featuring Eric Clapton on the slide guitar.

The version of the 1971 song was recorded during an impromptu performance at a birthday party for Keith Richards in 1970.

Richards is said to have considered releasing the version of the famous rock song on the band’s album Sticky Fingers, but decided to keep with the original.

The Eric Clapton cut will feature on the band’s upcoming reissue of their acclaimed 1971 album, which is due to be re-released on 8 June.

After marking their 50th anniversary with performances at Glastonbury and Hyde Park in 2013, the group have recently released an acoustic take of “Wild Horses”, an extended recording of “Can’t You Hear Me Knocking” and an alternate take of “Dead Flowers”.

Mick Jagger has said he would like to make a new record with the band soon.

The 71-year-old told Rolling Stone it “would be very nice” to make a new album with the band, adding he has a “lot of new songs” from the past two years.

The group are due to play their first dates in June since their saxophone player Bobby Keys, who was nicknamed “Mr Brown Sugar”, died in December aged 70.
