Paul O'Grady is our host as we take a trip through the magical history of the musical genre. The programme takes in everything from it's early 20th Century roots, through the 1950s technicolour classics and into the 21st century revival with the likes of Chicago, Moulin Rouge and Mamma Mia. There are contributions from James Corden, Michael Ball, Benny Andersson, Scott Baio and Michael York. In addition, Paul also speaks to the cast and crew of Les Miserables who discuss the process of singing the whole score live on set.
