Documentary revealing the fascinating story of one of the most famous music venues in the world, The Cavern in Liverpool, to mark the 50th anniversary of The Beatles' first performance there. Although the original venue is gone, there is a new Cavern on the old site - a place for new bands to cut their teeth, and a tourist attraction for Beatles fans across the globe. The programme includes interviews with members of some of the Merseybeat bands who also played in the underground venue, including Gerry Marsden and former Beatles drummer Pete Best, as well as playwright and Cavern regular Willy Russell.
