I really have to wonder if part of these types of discussions come from somewhere else.  (insert band name here) should stop so they don't tarnish their reputation, end up playing bars, get too old, etc.  Find me a musician that stops playing until health dictates otherwise.  Fame isn't the issue.  From the fan/critic point of view fame seems to be more of it.  How much of what our writer from Grand Rapids is saying is his own wish to hold on to his youth?  So what if Mick doesn't shimmy like he used to do?  I can't play tackle football with my boys the way I used to either.  Is seeing (name the band here) aging bothering him because his own youth is gone?
