STAGE

As if the acclaim his new musical “The Phantom of the Opera� is receiving on Broadway isn’t enough, Andrew Lloyd Webber may have a production of his earlier hit, “Cats,� hitting the stage in the Soviet Union. Vienna’s Theater an der Wien production of the musical captivated Soviet foreign minister Eduard Shevardnadze when he saw it in 1986, and a spokesman for the company said Tuesday it was “99% sure� the Austrian cast would give an English-language guest performance at Moscow’s Operetta Theater in May.
