In March 2009, Gary Barlow and mates Cheryl Cole, Ronan Keating, Chris Moyles, Fearne Cotton, Ben Shephard, Kimberly Walsh, Alesha Dixon and Denise Van Outen volunteered for a sponsored walk which was a bit tougher than they had imagined. They climbed Mt Kilimanjaro to highlight the deadly issue of malaria, and raised 3 and a half million pounds in the process. Now Gary and some of his pals return to Uganda to help distribute half a million malaria nets bought with Comic Relief money, and introduce the funniest moments from Red Nose Day 2009 - including French and Saunders' Mamma Mia, Smithy's England Sketch and Robert Webb's unforgettable Flashdance.
