Slavery lyrics

It will be forever true till we'll leave this planet blue Trying to free ourselves from that old slavery Everynight to God we pray Peace will come to earth one day Whether in the cradle, bed or grave, we're all the same While the earth goes on its way Does our principle within Change the colour of our skin? Thirst and hunger mix our wild extremes In every nature, every clime For future joys and presnt rhymes Then loved, and loving, man had lived and died The end's the same Strange power of song remains Strange power of song remains Strange power of song remains
