Blowin' in the Wind Lyrics

How many roads must a man walk down, before you can call him a man?
And how many seas must a white dove sail before she sleeps in the sand?
And how many times must the cannon ball fly before it is forever banned
The answer my friend is blowin in the wind, the answer is blowin in the wind
The answer my friend is blowin in the wind, the answer is blowin in the wind
The answer my friend is blowin in the wind, the answer is blowin in the wind
