THERE has been no announcement about the appointment of Ian Irish Commissioner for Expo 98 in Lisbon, and it seems that none will be appointed. This seems like a wasted opportunity. Opera Theatre Company has gone ahead and made contact directly with Expo, however, and will present Katya Kabanova, Tambulane, a double bill of a staged recital of Argento's From The Diary Of Virginia Woolf and Copland's The Twelve Poems Of Emily Dickinson in Lisbon in March of next year.
