Mariusz Kwiecien hurt his back at the Don Giovanni dress rehearsal (wah!).
High-profile new production, Luisi conducting, can't have a second-stringer stepping in for Kwiecien, so, a little shuffling of the Met schedule gets us PETER MATTEI taking over for Kwiecien! (At least for opening night.)
This increases the chances of my showing up for the HD broadcast, you betcha, if Mattei sings the full run.
Update: Cher La Cieca, or her spies, report that Dwayne Croft subbed in for Kwiecien for the balance of the rehearsal and apparently was the cover. Well, Croft is a good singer, but Mattei has a whole lot more animal magnetism going for him.
