I won't... I'll always play the drums.... even though my skills have deteriorated considerably. I adjust.. I don't attempt what is now beyond me. I can still keep a beat and frankly my 'nuance' may now be improved.
HOWEVER... I do not disagree completely with what is being said here. I noticed Paul having lost some vocal ability some time back. It didn't really irk me, however... he'll always be Paul and there is something in hearing the 'original' even if less than his early years... STILL.... the big concerts, charging top dollar? I agree, they should cut back.
