Wow! some do seem that long ago, others not. I have to admit I didn't know all of the hard rock ones.
Makes me think of re-watching last year "After hours"-Scorsese, such a great, quirky film that came out 40 years earlier in 1985.
And then realizing that 40 years before 1985, WW2 was just ending, which seemed like ancient history then. But '85 didn't seem that long at all.
Funny how perspective becomes more fluid with age.
