'EastEnders' star John Patridge, singer Charlotte Church and actress Sheila Hancock will join host Graham Norton on the new Andrew Lloyd Webber talent search series 'Over the Rainbow'.

The BBC One series will search for Dorothy and Toto for a West End production of 'The Wizard of Oz' and will air in the spring.

Commenting on the new show's judges, Lloyd Webber said: "We have a fantastic wealth of talent within our judges, and I know they're going to be bringing some incredibly valuable expertise and opinions in our search for Dorothy."

Norton and Lloyd Webber previously worked together on the BBC's musical talent searches 'How Do You Solve A Problem Like Maria?', 'I'd Do Anything' and 'Any Dream Will Do'.
