You could Google that in less than the time it took to type the post.
This will inevitably deteriorate into a thread about humorous song titles, but Roger touched on a very salent point. There are no songs about BEING old (or in my case middle-aged) at least not any new ones.
Interestingly, the Beatles wrote a couple of age-related songs (When I'm Sixty Four being one) when they were young men, but the Fab Four were musical artists in a long tradition of songwriters who wrote stuff that would touch something in other people, not production line pap such as we see today, in movies AND the recording industry.
So instead of providing examples of reworked song titles, I'd like to engage in a serious intellectual discussion on this.
Ah, bugger that. Some age-related song titles don't need to be reworked anyway.
