I loved these words and wanted to sing them.  I discovered a way to pair them with a well-known "campfire" song.  I then added the third verse, in addition to the first and last verses.  I am very happy with the song and enjoy teaching it to others.  It's easy to learn and very meaningful.

Lyrics

Come by here, Martin Luther King (3x)
Your words we sing (2x)
Darkness cannot drive out darkness
Only light can do that
Hatred cannot drive out hatred
Only love can do that
Vengeance cannot heal our wounds
Only justice can do that
Come by here, Martin Luther King
 Your words we sing
 Your life we sing.
