“Peter Hall, the eminent British director who oversaw four productions at Lyric Opera of Chicago, including a stellar new Otello in 2001, has withdrawn as director of a new production of Michael Tippett’s The Midsummer Marriage. The opera is scheduled to open Nov. 19. According to the Lyric, the move comes ‘on doctor’s orders’ for the 75-year-old director. Hall has not been feeling well over the past few days, and he leaves for his home in London today for medical tests.”
