The NPR recap does a nice job of hitting upon the highlights, but my two favorite moments had to be when Scott Simon referred to Jamie/Matt as the "cute one" in the partnership, then asked Mr. Walsh if that was the wrong thing to say. And as the interview ends, Bradley throws in a "Dun Dun".
Also, Jamie doesn't understand why the British can't get over the wig tradition. I think the American in him is showing. ;)
