I've been hearing that the new Arcade Fire album (which we have in the studio and I played a track from tonight on the show) was named after a John Kennedy Toole book. Having just read Confederacy of Dunces for the second time, I was under the impression that that was the only book he'd ever written before committing suicide. After some research, I learned that was sort of true; however, he did write a book called Neon Bible when he was 16 years old that was eventually published after Confederacy won the Pulitzer posthumously. (Of course, the amazon reviews in that link are already referencing the Arcade Fire album).
Anyhoo, if you haven't read Confederacy of Dunces and enjoy the absurd, go read it now.
