There was a Strawbs song called "Martin Luther King's Dream" that went thus:

^^ "Martin Luther King's Dream" (Dave Cousins)

(First Recorded on "Just a Collection of Antiques and Curios" in 1970)

"Speak only with your voices
And not the sword
Listen to your leaders
And the words of the Lord.

Chorus: Shake hands with your brothers
Has been my theme
For I have had a dream.

While fury gathers around you
Provoking you to hate
Remember what I told you
Don't heed the dangled bait.

The leaders of the country
Are speaking much the same
As those who've gone before them
And those who are to blame.

Proclaim a day of mourning
And let the flags fly low
The future is before us
As I have told you so."

Not the greatest of lyrics, but I recall it as a reasonably popular chorus number in the Strawbs' repertoire.
