Villazon out, Alagna in

So Rolando is really sick... He just pulled out of the first two performances (Sept.25 & 29) of the upcoming MET's production of Gounod's Roméo and Juliette. He will be replaced by Roberto Alagna, whose recent Manrico in Orange was controversial (that I have yet to watch).
Youtube extracts of the Trovatore production in Orange (July 31):
"Ah! sì, ben mio" ; "Di quella pira".
