How could we forget Marvin Gaye

In the category of good song with nutty, hippie lyrics Marvin Gaye’s “Mercy Mercy Me (the Ecology)” could be on the top of the heap.

Mercy, mercy me,
Ah, things ain’t what they used to
be, no, no.
Oil wasted on the ocean and upon
our seas
fish full of mercury,

Oh, mercy, mercy me.
Ah,
things ain’t what they used to be, no, no, no.
Radiation underground and in the sky;
animals and birds
who live near by are dying.
