In this special one-off documentary, host Bradley Walsh relates the history of the London Palladium and how it came to be one of Britain's most famous theatres. Bradley goes behind the scenes to discover the Palladium's history, its backstage secrets, and meets many of the stars who have performed on its stage through the years.
