It isn’t every network news anchor who could inspire a collection of America’s finest musicians to take to the stage of Carnegie Hall in celebration of his memory, but as has been abudantly clear since his death from lung cancer, Peter Jennings wasn’t just any anchor. A memorial to the Canadian-born journalist held at the famous venue yesterday drew 2,000 spectators. “Reflecting Jennings’ eclectic and wide-ranging taste, performers included cellist Yo-Yo Ma, trumpeter Wynton Marsalis, violinist Natalie MacMaster, and the Gates of Praise choir.”
