Be sure to check back here on parterre.com at noon (17:00 GMT) tomorrow for the First Unnatural Acts of Opera Gala and Quiz, featuring performances by Leontyne Price, Placido Domingo, Beverly Sills, Simon Keenlyside, David Daniels, Regine Crespin, Piero Cappuccilli, Regina Resnik, Diana Soviero and Eleanor Steber. (There will be some filth as well, but you’ll have to listen to the show to find out who the perpetrator is.) The quiz will consist of three opera-related questions; the first email received will win a pair of tickets to the English National Opera’s Billy Budd; three runners-up will receive historical opera DVDs. You can listen to the show directly through a link on this page beginning at noon, or you can download the show through Itunes. Until noon, then!
