What about when you have "lost it" due to age??

I am thinking of a very keen local chap who absolutely LOVES the limelight, but can't accept that he no longer has what it takes to be in the least Entertaining - or even listenable! (e.g. he has a quiet warbling voice that can't stay in key and gives long rambling introductions in his quiet, heavily accented, voice) His songs are just not recognizable! (and nigh-on impossible to sing along with).

If asked to do just one, or maybe two items, he'll always attempt to do more - sometimes very cunningly!

Some of the audience consider he should always be given a go, purely as a mark of respect for his age (he's over 80), whereas many others find it a very painful experience and if they could get up and go to the Bar without being too obvious, they would!!!

He is the bane of the MC's too!

Any thoughts?!
