The surgery is scheduled between June 2 and June 4, and he will then need a recovery period of six weeks, according to Ines Toston, a spokeswoman for the Teatro Real. The AP also quotes Miguel Lerin, Alagna's manager in Spain, as saying the surgery is "a minor operation" on the singer's septum and "not at all serious."
The Sicilian-French tenor had been scheduled to sing the role of Manrico three times during Trovatore's June 7-29 run at the Real.
His official web site at Universal Music says, "Because of the various rumors that have been circulating on the Internet and in the newspapers about Roberto Alagna, he would like to reassure his fans. He is in very good health but he has to cancel his engagement in Madrid in order to have a general check-up and rest for a few days."
