I once conducted Beethovens third overture to Leonore and
   directly afterwards Luigi Nonos Il canto sospeso.  To avoid
   a gap there was a reading from a letter by a camp prisoner
   of 1945.  The man had written: In Beethovens opera the saving
   trumpet sounds, but never for me.  No one applauded after the
   overture, the music went on without interruption.  A lot of
   people came to me afterwards and said: Now Ive understood
   something.
