1969

The final season of Mad Men is set in 1969.  I'm sure they've asked themselves how can they capture the mood of that long-gone era.  As noted below, there were new sounds, like the Moog synthesizer, that conjure up a certain sense of what is was like.

But I've recently come across some video, shot in 1969, that I believe encapsulates better than any other what it felt like to live in that time.
