First up – 70 is old. I know you're going to look younger and be healthier if you've been a millionaire all your adult life and a veggie for a lot of it, but 70 is sill old. He won't be able to play three hours very much longer.
The voice – I think he overdid himself in Mexico/South America. He has to be careful with it. In 2010 over here he played a couple of nights in a row and the top end goes. One gig every two weeks? I don't know if that's the answer. Play in a lower key? He's never done that (except I Will in 2005).
His bottom end, though, is still rich – check out All My Loving from the other night. So he has options to try something a bit different - something more low-key. But will he break the habit of a lifetime and do something interesting with his live shows? who knows




But I really think a voice coach would fix his problem. His voice is still powerful, it's just me needs to get it under control again. I feel he's breathing wrong - his nose sounds blocked when he sings now - and I think he is screaming from the "wrong place" - I really think its resolvable - well - to an extent. I don't think it's 100 % age - listen to Little Jimmy Scott, Tom jones, and more stomach turningly Engelbert Humperdinck and Cliff Richard- all in excellent voice and older than Paul. I think some training and a touring break will sort it. As I clutch my straws. A break helped before - he was a disaster at Glastonbury but gave some amazing performances in the subsequent tours...... Argh! This is quite sad!
