If you've never seen or heard it there's a short extract:
It's worth a look. We now know that King had feet of clay but that doesn't diminish his achievements or detract from his courage. It's hard now to believe that Uncle Sam - defender of the free, evangeliser for the cause of 'mocracy everywhere - could be just half a century ago a place where blacks and whites went to separate schools, ate at separate cafes and travelled on different buses.
King's dream - that his four little children might one day live in a nation that will judge them on the content of their character rather than the colour of their skin - might still be some way off being fulfilled but the promised land might be a little nearer.
And if it is, that's thanks in no small part to a dreamer. Its good to dream; I have a dream; we all do. And keeping those dreams alive helps banish our nightmares.
