Might I suggest "Beautiful Fool" by Don Henry:

Martin Luther, who did you think that you were
Appointed by some higher up
Merely mortal, you're plans were unaffordable
Nobody wants to pay the price for love

Oh, you beautiful fool, swimming upstream, kicking up waves
Dreams weren't meant to come true, that's why they call 'em dreams
Oh, you beautiful fool

Walter Cronkite preempted Disney one night
And all us kids were so upset
We thought that you were a trouble instigator
Marching through our TV set

Oh, you beautiful fool,.............

To fight a fight without a fist, all human instinct puzzles this
How dare you threaten our existence?
Mahatma Gandhi, Jesus Christ, history repeats itself so nice
Consistently we are resistant to love

Oh, you beautiful fool........

Saw you on the black and white with blacks and whites applauding you
Saw you on, another time, without a sign of life in you

Oh, you beautiful fool.......


I think this song is a tribute to MLK, a dreamer of dreams and all other beautiful fools like him who dare to dream things we cannot imagine and make them a reality...
