Back then I enjoyed those moments and I listened to that song as it was the only chance to ever listen it. When it was finished I didn't know the song's title, nor the vocalist. But thanks to Google and to "la, si, do, la, fa" I remembered from lyrics, I listened it again and again since then and still can't get enough of it. The song is Il maestro di violino.
And the singer (unknown to me until that day):
Yes, he's the guy, and he's the one who sang "Volare" and "Ciao, ciao bambina" for the first time. Those two songs are so popular, and he's not (probably he is popular in Italy, but internationally, not at all; or, at least, that's my feeling).
He was not only singer and songs author, but also a charming actor. He played in 45 movies, including "Il maestro di violino" and "Piange il telefono". The song Piange il telefono is one of my favorites, too.
I love that he was not simply singing, but he was putting a lot of passion in his music:
La lontananza, Come hai fatto, Dio come ti amo.
And he left not only huge artistic heritage, but also beautiful life heritage in his three sons Marco, Marcello e Massimo. Here singing together with Massimo: Delfini.
He surely made a better world!
P.S: thanks everyone for participating to my poll! Here are the results, showing the sad fate of a great artist not popular as much as he should...
