Gary Barlow and Melanie C will perform at an event celebrating 'Team GB' and 'Paralympics GB' at Royal Albert Hall on May 11.
In his ever-intensifying effort to be knighted by the end of the year, Barlow will headline 'Our Greatest Team Rises', a 3,000-capacity sit-down dinner which will raise funds for Britain's summer sporting efforts.
The eternal do-gooder said he was "absolutely delighted to be involved", remarking that the event "will play such a crucial role" in raising the money needed to support the athletes.
Meanwhile, Mel 'Mel' C has been given the dubious title of Party To 2012 Artist Chair, a role which involved her bringing together "Britain's biggest names" for the 'gig'.
These names include Alfie Boe and Spellbound.
