Choirmaster Gareth Malone brings together an array of untrained voices from the world of television, sport and theatre to release the official 2014 BBC Children in Need single. Actresses Alison Steadman and Linda Robson will sing alongside EastEnders actor Nitin Ganatra and Strictly Come Dancing's Craig Revel Horwood. Also searching for their inner songbird are Countryfile's John Craven, Blue Peter's Radzi Chinyanganya, Bake Off co-host Mel Giedroyc and comedian Jo Brand. Fabrice Muamba and Maggie 'The Machine' Alphonsi join the choir from the world of football and rugby respectively, and the line-up is completed by Radio 1 DJ Alice Levine and actor Larry Lamb. In the second of this two-part documentary, Gareth and his choir undertake a promotional tour across the country to drum up support for their charity single. They put their nerves to the test in preparation for their final showcase performance at Children in Need's Evening With the Stars at London's Grosvenor House Hotel, performing to an invited crowd. Will the choir be able to find their voices in time, and will the single see Gareth Malone return to the top of the charts?
