Actually I think Tom Jones has changed his style completely in recent years (sorry Andy). The voice has become softer and more soulful. He has improved with years
I'm certainly with Lottie about Cohen writing great songs, but singing dreadfully. A bit like Dylan in that repsect. And Tom Jones does have a superb voice.
(Sorry, Lottie, but I do quite like Gilbert & Sullivan. I was never that keen on Gilbert O'Sullivan though if that helps)
