Mick Jagger's still got it, I'd like to hear Rod trying some of his early stuff before passing judgement, but it's true that some singer's voices go, Macca springs to mind, and others seem just the same as always.
Went to see a 60's show a few years ago and they wheeled Chris Farlowe out, he looked awful, overweight and with this massive Hawaiian shirt on, we feared the worse, but when he started singing Out of Time he sounded just the same, a jaw dropping moment, after he'd done the compare said he'd be back when he's had some oxygen, I think he was only half joking
