Documentary examining how the BBC's flagship pop show reflected changes in British music and culture during 1976. As the popularity of glam rock faded, no dominant musical scene emerged to replace it, leading to chart success for bands including Abba, Showaddywaddy, the Brotherhood of Man and the Wurzels - while outside the mainstream, punk rock was rapidly growing in popularity. Featuring contributions by Tony Blackburn, Paul Morley, Toyah Willcox, David Hamilton and Dave Haslam
