lady love , go back to sleep , dry the tears from your eyes , but i cannot stay with thee , until the morning , for the dawn is breaking , and my ship is waiting for me , and i must go , but i'll be back , yes , before this year is over ; and we sailed across the sea , till we found america , 'round the cape of storms , we set our sails for home , and when the sea was roaring , and the lord i called , to help my drowning men , i saw the light , yes , the candle in your window ... and i have brought you silver , and i have brought you gold , and spices from the indies in the hold ; i've seen ships on horizon , that i'd swear were going down , and now i know for certain , the world is round , i have seen , my eyes have seen . oh , one day says galileo , a man will reach the sky , and see the world completely , from outside , and gazing down from yonder , on a world of blue and green , he'll say with eyes of wonder , i have seen , my eyes have seen , my eyes have seen .
