Blowin' in the wind

Blowin' in the wind
How many roads must a man walk down
Before you call him a man?
Yes, 'n' how many seas must a white dove sail
Before he can sleep in the sand?
Yes, 'n' how many times must the cannon balls fly
Before they're forever banned?
Refrein:
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, 'n' how may years can some people exist
Before they're allowed to be free?
Yes, 'n' how many times can a man turn his head
Pretending he just doesn't see?
Refrein
How many times must a man look up
Before he can see the sky?
Yes, 'n' how many ears must a man have
Before he can hear people cry?
Yes, 'n' how many dead will it take 'till he knows
That too many people have died?
