In 'Don Giovanni' at the Castleton Festival, one key player is missing

An ailing Lorin Maazel was nowhere to be seen at last Saturday's opening performance of "Don Giovanni" at the Castleton Festival (he didn't conduct the previous week's "Madama Butterfly" either but attended and addressed the audience). Given the extent to which Castleton's viability rests on both his artistic stature and his fundraising contacts, his indisposition invokes serious concern for the future.
