Blowin' In The Wind lyrics

How many roads must a man walk down before they call him a man
How many seas must a white dove sail before she sleeps in the sand
And how many times must the cannonballs fly before they're forever banned
The answer my friend is blowin' in the wind the answer is blowin' in the wind
[ Lyrics from: http://www.lyricsmode.com/lyrics/d/dave_dudley/blowin_in_the_wind.html ]
How many years must a mountain exist before it is washed to the sea
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 he just doesn't see
The answer my friend is blowin' in the wind the answer is blowin' in the wind
[ harmonica ]
How many times must a man look up before he can see the sky
How many years must one man live before he can hear people cry
And how many deaths will it take till he knows that too many people have died
The answer my friend is blowin' in the wind the answer is blowin' in the wind
How many roads must a man walk down...
