ARAFATA NON GRATA

Aides to Mayor Rudolph Giuliani quietly asked Yasser Arafat to leave a special New York Philharmonic performance of Beethoven's "Ninth Symphony" Monday night because he was not invited, the Associated Press reports. Giuliani had said that the PLO leader and Fidel Castro were not to join other dignitaries in town for the U.N. celebration, but Arafat turned up in his highly-visible, checked headress anyway.
