THE WAR’S IMPACT

Dampened Dancing: Because of security problems, Martha Graham has called off performances of her dance company at the Paris Opera that were to start today. The American Guild of Musical Artists--the dancers’ labor union--informed the dance troupe that because of the Middle East crisis it will not allow the dancers to travel to Paris for the weeklong engagement. The cancellation will leave the company with $140,000 in expenses that would have been covered by the Paris Opera production. . . . The Joffrey Ballet, which opens a two-week Far East tour on Saturday in Taiwan, will perform as planned, according to a spokesman.
