New commenter androgenous says, “I think we are getting a little ahead of ourselves by dismissing Calleja. Rehearsals have been long at the MET and I would presume that if Calleja was found to be inadequate they would have thrown him out or at least had a better replacement.” 

La Cieca realizes she is trampling on the God-given right of anonymous internet tough guys to authoritatively predict the trajectory of an entire career based on hearsay about one act of a rehearsal sung by a sick man, but she’s taking androgenous’s side here. If you axe-grinders must grind your axes (despite the lack of any solid evidence), maybe you should grind them elsewhere. The “dogpile on the tenor” game here is, frankly, making La Cieca nauseous.
