Blowing in the wind - Bob Dylan

How many roads must a man walk down

before you call him a man

(yes 'n') how many seas must the white dove sail

before she sleeps in the sand

(yes 'n') how many times must the cannonballs fly

before they are forever banned?

How many years can a mountain exist

before it's washed to the sea

(yes 'n') how many years can some people exist

before they're allowed to be free

(yes 'n') how many times can a man turn his head

and pretend that he just doesn't see?

How many times must a man look up

before he can see the sky

(yes 'n') how many ears must one man have

before he can hear people cry

(yes 'n') how many deaths will it take till he knows

that too many people have died?
