Just try and think of something unusual, that he wouldn't have been badgered about before! I asked him about bringing back "Why" at his London book signing and he seemed genuinely startled by the question and we had a lovely chat. I'm tiring of the Kremlinology that we're having to endure about the new album! If you must, maybe ask him if a Lindsey/Chris-based Mac EP might come out in the meantime? That might coax she-who-must-be-obeyed to at least contribute some backing vocals...

If you're really stuck, ask him how Danny Kirwan is or for more details about Peter's playing on
Brown Eyes, or even if that song might be on the setlist for the next leg of the tour, or if it might be included when they hit the UK.
