Comic Relief's Big Chat With Graham Norton is set to run all all night without trailer breaks, so the host will be assisted by co-presenters. The full list of co-hosts has yet to be revealed but the BBC says it will be using "chat-show veterans such as Sir Terry Wogan and Frank Skinner."
Radio 1 DJ Nick Grimshaw, who was recently signed up to host new panel show Sweat The Small Stuff for the channel is also said to be acting as a co-host for one of the segments. The BBC says: "The co-hosts will ensure Graham remains on track to hopefully smash the world record and raise as much money as possible for Comic Relief."
Additionally, model Elle Macpherson, actor James Nesbitt, chef Heston Blumenthal, gymnast Louis Smith, JLS singer Aston Merrygold, dancer Ashley Banjo, singer Kimberly Wyatt, presenters Alex Jones and Steve Jones, and presenter Kirstie Allsopp appear on the guest list.
Norton says: "David Walliams swam the Thames, John Bishop endured a week of hell and Eddie Izzard ran marathon after marathon after marathon. I am hoping to join this elite group of celebrity fundraisers by doing what I do best - sitting on my backside and talking."
In addition to the above, Radio 1 DJ Greg James will host Big Chat Backstage Party, talking to the guests in the green room before their interviews with Graham.
