Music 4

Music 4 have produced the theme tune for all the coverage of The Big Climb for Comic Relief 2009 on BBC Radio 1.

Chris Moyles, Fearne Cotton and seven other brave celebs have gone to Africa for one of the biggest challenges of their lives....they are walking for seven days to the top of Mount Kilimanjaro in Tanzania to raise money for Comic Relief.

Chris and Fearne are climbing alongside Cheryl Cole, Kimberley Walsh, Alesha Dixon, Ben Shepherd, Ronan Keating, Denise Van Outen and Gary Barlow.

In addition to the main theme for the coverage of the climb on Radio 1, while Chris climbs the mountain, Vernon Kay is presenting the Breakfast Show and we've customised Chris' jingles to reflect this on-air change.
