Mick Jagger is heading up a band named SuperHeavy. Also in on the project are Joss Stone, AR Rahman (composer of the Slumdog Millionaire soundtrack), Dave Stewart (the former Eurythmic) and Damian Marley. It seems outlandish and the product of an overheated PR person’s imagination, but many things in life can be both. Yet, this is real, not an April Fool-type joke.
A single, titled “Millionaire”, is supposed to come out in September. The producers are Jagger and Stewart. Rahman has written a song called "Satyameva Jayate”, which Jagger is to sing in Urdu. Presumably, he does speak Urdu.
Probably not most people's idea of world music.
The evidence so far is below.
