Catching up...here's a link to a RealAudio clip of This American Life. Skip ahead to 22:55 to hear Sarah Vowell talk about "The Battle Hymn of the Republic." Regarding the controversy between "let us die to make men free" and "let us live to make men free," she says: "In my opinion, die is the way to go. When you get rid of the word die, you erase the most moving idea in the song, that if Christ died for us, we should be willing to die for each other--why give that up? This is the one clear-cut case where you can ask yourself, 'What would Jesus do?' and you know the answer. What would Jesus do? Die."
