We have a ton of astronomy audio content laying around here at Slacker Astronomy. We have our entire podcast feed, which dates back to February 2005 and spans entire epochs of Slacker Astronomy casts and styles. Then there is the little known Extra feed which has tons of interviews and oddball content. We also have our Slack Video Feed, which has random videos from over the years.
Poke around those and you might find some entertainment. For example, there is this little gem of an interview with David Levy!
