BBC's The Voice 'should have been on the radio', says Simon Cowell He said the show, which features Jessie J, will.i.am, Danny O'Donoghue and Tom Jones as coaches, was "the same as X Factor, they've got dancers behind them, they've got graphics, lights, same show." The Voice coaches Danny O'Donoghue, Sir Tom Jones, Jessie J and Will.i.am singing at the first live show. Describing himself as "lucky, hard-working and weird," he went on to discuss how he felt "nervous" about the X Factor because he felt only Leona Lewis had gone on to prove herself in the music industry. "We had this conversation about two or three years ago where, with the exception of Leona Lewis, I was getting nervous and I thought if we don't find real stars from these shows after all the razzmatazz, all the promises, all the hype and you end with somebody whose going to put out a single and then go away it's a waste of time, a waste of my time and everyone's time," he said. Asked whether he felt his shows exploited its participants, he said his experiences with Susan Boyle, the surprise hit on Britain's Got Talent, made producers more aware of performers' vulnerabilities. The 52-year-old said: "Everyone is very very more aware of whether this person is up for this or not. If we don't think they are tough enough, they are not even allowed to audition. He ended by saying he was motivated by his desire to win and confirmed he was working on new show formats. Follow Telegraph TV & Radio on Twitter
