I can't help but agree with Rick Nelson:

I went to a garden party to reminisce with my old friends
A chance to share old memories and play our songs again
When I got to the garden party, they all knew my name
No one recognized me, I didn't look the same

CHORUS
But it's all right now, I learned my lesson well.
You see, ya can't please everyone, so ya got to please yourself

....

If you gotta play at garden parties, I wish you a lotta luck
But if memories were all I sang, I'd rather drive a truck.


I suspect people who get stuck on one musical era aren't reacting to the music, but the era, and that era is where they live. Adding other music means leaving home.
