That's true. I can see that.
But here's a BIG difference, in my opinion:
The decade of the 60's was really one of extreme change of perception in this country. This was reflected in many social protests and otherwise "rebelliousness" of the time.
Because the music was so seminal in getting the messages of change through the radio and television and through live concerts and all sorts of new socially-conscious action, the world stopped taking everything that was fed to them as being the gospel truth. It was the decade when people really began to question their government (and rightfully so!).
It was the age of mind-expansion, love-ins, hippies, rock concerts. Essentially there was a movement to try and find a way to get along with each other -to end segregation.
Of course, it didn't really pan out as intended. And most of those old hippies eventually ended up wearing suits and working for "the man"! When the decade faded from the 60's and into 1970, it started out seeming a lot like the 60's had ended. But, by the time 1980 hit, things were completely different from the way things had been at the start of 1960...ya dig? ;)
That's how time works....slowly....but relentlessly! You don't see it coming.Car Driving2Eye Ball
My point is that, just like old side drums from the Civil War are relevant to their own time/history, so will the drums and sets from the 60's.
So I would expand upon your point to say that these are the things that we wanted as kids and they were also instruments of social change tied to that era.
