From Tribute Album "Marvin is 60!"   Written by Marvin Gaye      Woo oh, mercy mercy me    Oh things ain't what they used to be, no no       Where did all the blue skies go?   Poison is the wind that blows from the north and south and east      Oh mercy, mercy me   Oh things ain't what they used to be, no no      Oil wasted on the ocean and upon our seas, fish full of mercury      Ah oh mercy, mercy me   Oh things ain't what they used to be, no no      Radiation under ground and in the sky   Animals and birds who live nearby are dying      Oh mercy, mercy me   Oh things ain't what they used to be      What about this overcrowded land   How much more abuse from man can she stand?   Oh, na na...
