Despite numerous times of seeing and hearing the famous "I have a dream" section of Martin Luther King's speech, I'm not sure I've ever viewed the entire 16-minute speech (which is only about 1600 words). A video of the entire speech, delivered August 28, 1963, is below. The famous section starts at about 12:20.
I'm ashamed to say I hadn't watched the whole thing either until now.
For another great video with MLK, watch Let Freedom Ring.
