"Preacher man don't tell me heaven is under the earth
I know you don't know what life is really worth
Is not all that glitters in gold and
Half the story has never been told
So now you see the light, aay
Stand up for your right..."
from "Get up Stand up" by Bob Marley and the Wailers
It is a reggae song written by Bob Marley and Peter Tosh.
Album: "Burning" - 1973
