There was great complicity and great affection between Franco Battiato and Rosario Fiorello, both Sicilians, both from Catania.
At the time of Viva Radio2, the Maestro was willing to exchange his voice with that of Fiorello, who imitated him in a credible way.
Once the showman launched a song on Radio Deejay, 'Mare nostrum', with a delirious text, which made the verse to the more complex songs of Battiato, and many fell for it thinking that it was a new single from the singer-songwriter. "What do the unmarried herring know about the rituals of the Baltic cod at this end of the century. What do the apathetic mussels know of the mood of lively squid at the dawn of the third millennium ...", sang Fiorello. It was Battiato himself who told the anecdote on several occasions, laughing and lovingly reproaching him.
