JLS Singing for Charity

British boy band JLS are using their vocal skills to raise money for charity - they're recording the official single for the U.K.'s Sport Relief campaign.

The band has written and recorded a song called Proud as a soundtrack for the charity, which aims to raise cash for good causes via sporting events.

The track will go on sale as a download on 18 March (12) before it is released in stores a day later (19Mar12), and the group is also taking part in a one-off concert for the campaign later in the month (24Mar12).

Jls are not the only stars to be raising funds for Sport Relief this year (12) - British singer Olly Murs, actress Kara Tointon and former Olympic rower James Cracknell have been sponsored to run the Sport Relief Mile.
