Dance of the Daleks

How do you make a sink-plunger seem scary? Matthew Sweet, who spent the Saturday tea-times of his youth peering at the television from behind the sofa, time-travels through Doctor Who's 47-year history to investigate the weird and wonderful soundworld of its incidental music. He talks with some of the composers who have contributed, in very different musical styles, to the enduring success of the programme over the decades.
