Puzzling

A rather strange edit in this week's NPR "Sunday Puzzle": there's a chunk missing -- it's round about the 4 minute 30 point in the podcast version, but it was also the same on the broadcast version. The answer to one clue is given in respondse to a different one, so one answer and one clue are missing. You'll probably have to listen to the whole thing to understand what is going on, though.

So, your puzzle of the week: what is the missing answer and missing clue?
