A.R. Rahman did not need two Oscars to prove his musical genius, but those two shiny statuettes have won him some really coveted opportunities in the global music scene. The latest enviable association he has made is with former Rolling Stones member Mick Jagger for a song that will be released on United Nation’s International Day of Peace on 21st September. Apart from ARR and Mick Jagger, the others who will be coming together to make this track are rapper-actor Nas and Jamaican musician Bob Marley's sons Damian and Stephen."Joss and Mick hit it off when they worked with producer Dave Stewart on the 'Alfie' soundtrack, so were keen to collaborate again. When this project was suggested they were keen to get on board, especially considering the glittering cast of other musicians involved," an informed source revealed.
