Charlotte Church, EastEnders star John Partridge and veteran actress Sheila Hancock were unveiled today as the judges in Andrew Lloyd Webber's latest TV talent search, Over The Rainbow.
The new expert line-up of stars will give insight and opinions to help viewers decide who will make the perfect Dorothy.
The BBC1 show, which airs this spring, will reunite host Graham Norton with Lloyd Webber in the hunt for a star for an updated version of The Wizard Of Oz in London's West End next year.
Lloyd Webber said: "Each member of the panel brings something new and exciting which will take Over The Rainbow even further than the previous shows."
Partridge, who is known to EastEnders viewers as lovelorn Christian Clarke, has a musical theatre background. His first appearance on stage was on tour in Lloyd Webber's Cats, playing Rum Tum Tugger.
The actor said: "Musical theatre has always been my first love, so I'm hugely excited to be joining the panel."
Hancock also has numerous musical theatre credits and is appearing in the stage version of Sister Act. Hancock said: "I've had such an interesting and varied career and I'm so looking forward to working with Andrew to seek out some fantastic new talent."
Church was catapulted to fame at a young age, with the release of her multi-million selling debut album Voice Of An Angel in 1998. Church said: "My career started with Pie Jesu, which was of course written by Andrew, so it feels like I've come full circle."
Aoife Mulholland from Salthill, Galway, came to fame in 2006 on the hit BBC TV show How Do You Solve A Problem Like Maria? She performed for 18 months as Maria von Trapp in The Sound of Music at the London Palladium.
