Say what you will about all the downsides of rock stars getting old, but there are some themes that only make sense coming from an older perspective. Feeling threatened by younger, better looking rivals is one of them. A young Mick Jagger would never be threatened by any other man. A Mick Jagger in his 50’s could be forgiven for worrying about getting traded in for an upgrade. For an egomaniac rock star who’s used to being on top of the world, aging provides an opening for showing a more vulnerable side, a chance to write about something other than being the cock of the walk. I think it’s no coincidence that The Rolling Stones have produced some really outstanding ballads in their later years.
