It's a Revolution Mother1969

Synopsis:

This documentary depicts the wild swinging youth scene of the turbulent 60's, with in-depth footage of hippies doing a protest march against the Vietnam war in Washington, D.C., a rowdy New Jersey biker club called the Aliens letting it all hang out, and kids having themselves a groovy good time at a funky Florida rock festival.
