As La Cieca’s clever public guessed six weeks ago, Renée Fleming is not going to sing Norma.

“The part just didn’t fit as she had hoped it would after living with it,” Fleming publicist Mary Lou Falcone said Thursday to the Associated Press. La Fleming, 48 (though she doesn’t look a day over 20, does she?), will perform Eugene Onegin under the baton of James Levine next summer at Tanglewood instead of the Bellini work.
