During the intermission of the October 29 Metropolitan Opera performance of Guillaume Tell, audience member Roger Kaiser tossed a white powder into the orchestra pit. As a safety precaution, the company canceled the rest of the show, as well as Saturday night’s performance of L’Ialiana in Algeri, while police investigated the situation. The powder turned out to be the ashes of Kaiser’s opera-loving mentor. Apparently, Kaiser meant no harm and had told several audience members of his plan.
