The members of the National Symphony Orchestra, now entering the second week of a strike, apparently will not go to Mexico City where six concerts had been scheduled between today and Oct. 8.

A spokesman for the striking musicians said the U.S. ambassador to Mexico had sought to arrange for the orchestra to appear without the full cooperation of management.

However, in a statement, the musicians said management "refused to compromise at all," adding "either we were going to do it (their) way or not at all."

The deadline for notifying the Mexican sponsors of the tour passed at 9 a.m. yesterday with no agreement between musicians and management.

Austin Kiplinger, newly elected president of the National Symphony Association, the orchestra's management, wired the Mexican sponsors shortly afterward, saying the trip would not be made.

At the same time he issued a statement expressing regret that "it is not possible to send" the orchestra to Mexico at this time.

The statement said that the association "felt that the orchestra should play a concert series in another country only under the optimum conditions provided by normal association sponsorship."

The musicians wished not to make the trip under association sponsorship while on strike, because that would have meant performing at the salary provided in the contract that expired that Saturday night.

On the other hand, the association owns many of the orchestra's instruments and all its music, and even to go without association, sponsorship would have required association cooperation.
