"Madness! Madness! Everywhere madness!" The unsung words of cobbler-philosopher Hans Sachs in the third-act prelude to Wagner's Die Meistersinger might seem like an odd opening manifesto for the Berlin Philharmonic Orchestra's annual May Day ceremonial concert this morning, hosted this year by Oxford in the gorgeous venue where the Berliners had last played under Karajan a very long time ago. But there was method in it.
