Blowin' in the Wind Lyrics

How... how... how... how... how?
No man, it's goes like this:
How many roads must a man walk down
Before you call him a man
How many seas must a white dove sail
Before she sleeps in the sand
And how many times must the cannon b**** fly
Before they are forever banned

The answer my friend is blowin' in the wind
The answer is blowin' in the wind
How many years can a mountain exist
Before it is washed to the sea
Yes and how many years can some people exist
Before they're allowed to be free

Yes and how many times can a man turn his head
And pretend that he just doesn't see
The answer my friend is blowin in the wind
The answer is blowin in the wind
The answer my friends is blown in the wind
The answer is blowin... in the wind
