Query: Why, why does Pavarotti do this to his career?

Why would a singer that had some great, even some monumental recordings under his belt (Fille du Regiment) do something like this? Oh, I know, money.Luciano Pavarotti was blessed with a great voice, but NOT a voice for singing Calaf. If you want to know how Puccini wanted his Calaf to sound find a recording of Giacomo Lauri Volpi or one of Franco Corelli. Fleta did the opening night of this Puccini's swan song, but he was wise enough not to sing it again (no recordings of Fleta on this role are available); I wish Pavarotti and other singers would have learned a lesson from Miguel Fleta.
