Icons, yes, but to remain an icon and avoid becoming a target of "understanding" nods requires a timely retirement or a change of style. The artist needs to be able to change with his increasing limitations. That way he maintains dignity and true appreciation.
Well put..................
I personally hate watching or any artist past their prime..........................
Unless , they appear to have an understanding of where they are now in there lives or careers, and appear to have made honest adjustments that are almost acknowledgments of their current skills.
That all being said, When its time to hang it up ,its time to hang it up.........
Sad but True......................
