The Opera Orchestra of New York has canceled its March 7 concert performance of Verdi’s “Simon Boccanegra” with Placido Domingo after a donor withdrew a $250,000 pledge.

The performance had been scheduled for Avery Fisher Hall at Lincoln Center for the Performing Arts.

“We have a mandate to be fiscally responsible, and with the loss of funding for this production, we were given no choice but to cancel,” opera board chairman Norman Raben said yesterday.
