Let's face it, Bob was never good looking, so he lost very little.
But I don't feel the need to see him; just to hear his songs.
And it must be 15 or 20 years since I last enjoyed his performance of his own songs; something has gone out of his delivery, for my taste. He still writes like the master he is, of course.
So let him write, and let others perform his stuff; and I will listen to my old vinyl and reconstituted CDs to remember and enjoy him as he was. Looking at him now simply reminds me of my own mortality - and I have plenty of reminders for that, I don't need to see my idols wither also.
