“You are not only responsible for what you say, but also for what you do not say”...Martin Luther King Jr.
The time of the civil rights movement was also the time of Vietnam war protests. A lot of the music from that time was interchangeable between the two, in the ideas put forth.
In "Blowin' in the Wind," Bob Dylan wrote "How many years can some people exist before they're allowed to be free. How many times can a man turn his head and pretend that he just doesn't see." The song also contains the line "How many times must the cannonballs fly, before they're forever banned."
A song that was sung on the steps of the Washington Monument along with Dr. Martin Luther King Jr., perhaps one of the greatest songs ever written...listen to "Blowin' in the Wind" performed by Peter, Paul & Mary.
