In a pinch, you can use a copyright-free version of the MLK speech. Sample:<p><pre><code>    &gt; &quot;I Have An Idea&quot;
    &gt;
    &gt; I&#x27;m super happy to join with you today in what 
    &gt; will go down as a noteworthy demonstration for 
    &gt; freedom in the history of our nation.  One hundred
    &gt; years ago, a great president --his statue is behind 
    &gt; me-- signed the Emancipation Proclamation.  Good
    &gt; stuff, that.
    &gt;
    &gt; I have an idea that one day we&#x27;ll will rise up
    &gt; and live out: &quot;We hold these truths to be 
    &gt; self-evident, that all men are created equal.&quot;
    &gt;
    &gt; I have an idea today!
    &gt;
    &gt; Free finally!  Free finally!
    &gt; Thank the Maker, we&#x27;re free finally!</code></pre>
