There is a rumor going around that the CIA was responsible for 60s music. For those of us who were there seeing our rock pundits get eliminated or co-opted, knew music was the people's medium of the time, and it was a battlefield.
Some songs evidently got past the censors. If the band was big enough. We need to remember those songs, which got cut from FM playlist. But inspired a generation, and changed the world forever. Unfortunately, the fight for freedom, and music, against censorship, is not over yet.
