Well, let's not forget Italian tenors like Tito Schipa and Fernando De Lucia, for instance. They were different, but both were absolutely top tenors, far before the time of Bergonzi and Callas. Maria Callas once said: "Nothing so bad for Italian opera's like Italian tenors." Di Stefano, who heard her that saying, said: "Sorry Maria, but I'm Sicilian." "That's even worse", Callas answered." But I think Callas didn't had Bergonzi, Schipa and Lucia in mind, when she made that statement. And I'm sure that she would have been very delighted if she could sing with Schipa and De Lucia. The inmens famous Lucia, once said to his later also becoming very, very famous student, Georges Thill: "Good...you are only a few times a year." De Lucia was absolute great in more than one way. De Lucia and Thill, maybe a nice project for Herur22.
