Jerry Springer got an opera. Why can’t Bill O’Reilly have one too?“Mackris v. O’Reilly,” the sordid tale of the sexual harassment charges filed by Andrea Mackris against Fox News’ red meat-eating pundit in 2004, preems in January at the U. of Washington — and it sounds a lot more highfalutin’ than “Jerry Springer: The Opera,” which was more of a comic tuner. “Mackris v. O’Reilly” is a 31-part oratorio that composer Igor Keller modeled on baroque classics like Handel’s “Messiah” and Bach’s “St. Matthew Passion.” Libretto consists of the original complaint filed by Mackris, broken down by Keller into arias, chorales and madrigals. But can O’Reilly be expected to tell a recitative from a motet when he doesn’t know his loofah from his falafel?
