If you are using a Windows based computer, click this
link. You'll see a row of pictures of the guests on the discussions.
Just to the right of the bottom right corner of each picture is a yellow button that says, "MP3."
Right click the image, then click "Save Link As..."
Then save it wherever you want. To listen to it on an iPod, you'll need to connect the iPod to your computer and open iTunes. Open Windows Explorer to the folder that you saved the MP3 in. Click and drag the MP3 into the "Music" section of your iPod in iTunes.
Got it?
edit: Next time, read more thoroughly. The link I provided is in the thread that cm763 linked to, and is also provided by Jon Raiker in this very thread.
