Please fellow fans do not think I'm Paul bashing. I never have and never will.
My point is that the public however may not be so kind if his voice was too deteriorate (which no human can avoid) much more.
I do not want to see him being degraded in the future that's all my point really is and that that will require difficult future judgements and decisions.
Yes his voices sounds okay for a 70 year old. But you could argue that a person's voice sounds good for a 90 year old - that
doesn't mean I would like to hear it.
Just like politics, you need to know when to go and when to change gear or direction or approach.
This is never easy for any indivudual to make especially when you are a musical giant!
