Heal the world
Make it a better place
For you and for me
And the entire human race
There are people dying
If you care enough for the living
Make it a better place
For you and for me
There are ways to get there
If you care enough for the living
Make a little space
Make a better place …
And if you really try
You'll find there's no need to cry
In this place you'll feel
There's no hurt or sorrow
There's a place in your heart
And I know that it is love
And this place could be much
Brighter than tomorrow
Enjoy the song
