I enjoyed it. I did not call in, but I'd have been star-struck and no doubt stammering the whole time anyway.
However, the questions I had did get answered through the folks who did call in.
The show began with a playing of the theme to The Challengers and following some brief opening remarks, our host introduced his guest and the show was off and running for ninety uninterrupted minutes.
I won't ruin any of the content for you since I believe the episode remains accessible, but as a fan of his since the days of Let's Play Post Office, it was a treat.
