Lord Lloyd Webber's quest to cast his leading Dorothy in the West End continues.

Host Graham Norton transports the final 20 hopeful girls to the magical studio kingdom of Oz in an all-singing, all-dancing extravaganza which marks the final stage of the audition process.

In their toughest and most glamorous audition yet, our final 20 potential Dorothys must convince the Lord and his all new panel (Charlotte Church, Sheila Hancock and John Partridge) that they have the essential leading lady qualities required to continue on the yellow brick road to west end fame.

But which girls will do enough to convince the Lord and the panel that they deserve a guaranteed place in next Saturday's live shows when they perform for the Nations votes?

Also on hand to share their expertise are five of the West End's hottest leading ladies: Ruthie Henshall (Chicago), Mel C (Blood Brothers), Kerry Ellis (We Will Rock You ) Tamzin 0uthwaite (Sweet Charity) and Sheridan Smith (Legally Blonde).
