THIS FRIDAY’S CONCERT in the Duck Hollow Symphony Pops series, Blueprint: A Symphonic Interpretation of the Music of Jay-Z, has been postponed indefinitely, because bassoon soloist Nicephorus Fernandez, who interprets the vocal parts, has come down with what an orchestra spokesman described as a bad case of second thoughts. Because the orchestra is flat broke, no refunds can be offered, but ticket-holders will be admitted free to next week’s concert performance of The Mikado, starring Kanye West in the role of Nanki-Poo.
