Paul O'Grady embarks on a feel-good journey in this special show celebrating the many highlights of the magical movie genre of the musical. A keen fan and aficionado, Paul leaves no musical note un-tuned as he reveals the genre's history - from its roots in the early 20th century, through its golden era, and all the way up to the multimillion dollar industry it has become. Paul is joined by a host of stars and insiders from the world of movie musicals, including James Corden, Michael Ball, Michael York, Joel Grey, Sheila Hancock and Benny Andersson. The musicals covered include Singin' in the Rain, West Side Story, The Sound of Music, Bugsy Malone, Mamma Mia! and Into the Woods. There are stories from the set of The Wizard of Oz, told by Judy Garland's daughter and Bert Lahr's son. Scott Baio, who played Bugsy Malone, reveals what it's like in appearing in a movie with no adults. And the directors and stars of Les Misérables discuss singing the whole score live on set.
