Will.i.am premiered his new single from Mars with the help of former The Voice contestant Jaz Ellington, it has been revealed.
Jaz, who was coached by Will.i.am on the BBC singing contest last year, lent the vocals of his school choir to the track.
Trained by Jaz, the fifteen students aged between 12 and 14 from Southfields Academy (at the time of the recording known as Southfields Community College) were asked to perform after Will saw them sing Beatles classic Let It Be on The Voice with Jaz during the quarter-final of the show.
The NASA rover Curiosity beamed to Earth the Black Eyed Peas singer's song Reach For The Stars, in the first music broadcast from another planet, to the delight of students gathered at the Jet Propulsion Laboratory in Pasadena, California, to listen.
The song had been uploaded to the rover, which landed near the equator of Mars, and played it back - a journey of some 700 million miles.
