 See, I apologize, folks. Going to be in your head all day. Nothing wrong with that, though. We're talking with Jeff Tweedy of Wilco. His new book is called World Within a Song, Music That Changed My Life and Life That Changed My Music. You know, one of the things that I like about the essays is that there's the opportunity for you to learn a little bit about how music works. An example is Randy Newman's In Germany Before the War. Can you talk a little bit about what this song taught you about songs as a whole?
