My wife and I attended a live performance of the NPR program Wait Wait... Don't Tell Me. It was very entertaining. The panelists were Charlie Pierce, Amy Dickinson and Mo Rocca. The scheduled local guest was planned as Governor Elliot Spitzer, however, as host Peter Sagal said "Some came up. (Then the governor paid $4000 and it went down again.)" I'll leave it there. In former governor's place was a large arrangement of flowers.
To my delight, the replacement guest was television celebrigeek Adam Savage from Discovery channel's MythBusters! He connected in from a studio in California and was interviewed for a good 20 minutes. It would have been far cooler to have him there, but it was fun regardless.
Having worked in radio for many years I am always interested to watch radio show production. This performance was no exception. They have call in contestants, a few sound effects and quick thinking participants that the producers and engineers have to work around. After the show completed they spend 10 minutes and went back through the show doing some re-do takes where they needed to clean up introductions or whatever. Having a large (~2600 people) live audience complicates it a bit as well.
Overall, it was a good time and a chance to get out the house.
