The link that Mark gave is a little confusing. The first two links to the Real Audio on that page lead to the recording of the first hour. Only the one on the very bottom lets you hear the second hour, which is the one with Dean. His segment starts 6:50 into that segment.
The direct link is:

I also have a 18mb MP3, if you need it, I can figure out some way to get it to you.
