Listen Against: the programme that looks back at a week's worth of radio and TV that never happened. It's a bit like the BBC iPlayer. only with two eyes instead of one. And it's got ears. This week, ecological and broadcast catastrophe strikes as BBC 3 leaks in to other channels, Edward Stourton and Gaby Roslin tunnel to the centre of the earth for Children in Need, and a preview of the new musical charting the dramatic lives of the Dimblebys: 'News Brothers'. With special guests Marcel Theroux and Julia Hartley-Brewer. Presented by Alice Arnold and Jon Holmes. Featuring: James Bachman, Stephen Critchlow, Sarah Hadland and David Schnieder.
