"Blowin' in the Wind"

"Yes, how many years can a mountain exist
Before it's washed to the sea ?
Yes, how many years can some people exist
Before they're allowed to be free ?
Yes, how many times can a man turn his head
Pretending he just doesn't see ?
The answer my friend is blowin' in the wind
The answer is blowin' in the wind."

Música original por Bob Dylan
