Los Angeles: Singer Tom Jones has revealed he is "back in form" following the death of his wife Linda. The 75-year-old, who lost his wife to cancer in April, says he is ready to perform again and has rediscovered his zest for music, reports mirror.co.uk. “I'm feeling pretty good now. I'm back in it and getting back in form,” Jones said. “It's been a tough few months, losing Linda. She had emphysema, and we thought that's all it was. But it turned out to be worse than that in the end,” he added.
