The Voice producers have asked Sir Tom Jones to spice things up a bit on the show as they fear he is becoming too boring. The Sun reports that the programme's crew had to talk to him during breaks in a bid to pep up his performance and were seen gesturing frantically at him when the cameras were rolling. An unnamed audience source said: "He called everyone 'great' and his responses were flat and awkward … It was obvious the crew were doing everything they could to get him to be more lively."
