Gingham dresses, pig tails and ruby slippers at the ready as thousands audition in the hope of becoming your Dorothy. After months of searching and auditioning, the final 50 girls find themselves having a tough time on Dorothy Farm, where the panel of Charlotte Church, John Partridge and Sheila Hancock pick the final 20 girls that could be your Dorothy.

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.

Host Graham Norton transports us to the fantasy world of Oz where anything can happen. The final 10 girls chosen by Andrew and the panel go head to head as they sing for the public's votes. And they're joined by the 11th wildcard Dorothy as chosen by the viewers. As well as singing for the viewers votes, the girls are desperate to impress our panel Charlotte Church, Sheila Hancock, and John Partridge.

The first results show of the series. Our final 11 girls are sent on their first Dorothy mission, where they'll muck in together and muck out... on a pig farm. But the Dorothys have one thing on their mind - which of them have persuaded the public that they deserve to stay in the competition? And which two girls have received the fewest viewer votes and must perform in the dreaded sing off? Lord Andrew Lloyd Webber will save one Dorothy whilst the other leaves the competition for good.
