Mick Jagger and Joss Stone set to record together

Sir Mick Jagger and Joss Stone are to record a song together.

The Rolling Stones frontman and the soul singer - who first collaborated in 2004 on 'Lonely Without You' for the 'Alfie' soundtrack - will perform a duet for a new album to coincide with the United Nation's International Day of Peace on September 21.

A source said: "Joss and Mick hit it off when they worked with producer Dave Stewart on the 'Alfie' soundtrack, so they were hoping to collaborate again. "When this project was suggested they were keen to get on board, especially considering the glittering cast of other musicians involved."

Mick and Joss have been working with Bob Marley's sons Damian and Stephen, rapper Nas and 'Slumdog Millionaire' soundtrack composer A.R. Rahman. The stars are currently working on the album at a Los Angeles studio, but there have been some disagreements about when recording should take place. Damian prefers to work at night, while Mick would rather record in the morning.

The source added to Britain's The Sun newspaper: "It's incredibly challenging to get so many figures in the studio at a time that's agreeable to everyone. "Damian's a night owl whereas Mick likes to hit the studio in the morning. They eventually reached a compromise where by they will record from 5pm to midnight every day."
