1. Earth song - Michael Jackson
what about sunrise
what about rain
what about all the things
that you said we were to gain...
what about killing fields
is there a time
that you said was yours and mine...
did you ever stop to notice
all the blood we've shed before
the crying earth the weeping shores?
aaaaaaaaaah aaaaaaaaaah
what have we done to the world
look what we've done
what about all the peace
that you pledge your only son...
what about flowering fields
is there a time
what about all the dreams
that you said was yours and mine...
did you ever stop to notice
all the children dead from war
the crying earth the weeping shores
