I listened to it. He actually gave more interesting info about the book on that show than at Politics & Prose. I was waiting for the guy who corrected his pronunciation because Chris mentioned him in his schtick. What an ass! He didn't even pronounce things correctly himself. There were two Parisian women at P&P, so he asked them how he was doing. They said just fine. Anyway, when I heard the guy and then Chris's answer, "No," followed by Kojo's commentary, I just cracked up.
Chris didn't speak for as long a time at P&P, but it may have been based on the size of the crowd. I think he shortened it so that he could get out of there by 10:30 or 11. I think we left at 10:45. They really pack them in.
