My father is a big fan of Ricchi e Poveri. I'm not that much into it, though they have few decent songs. I was in their concert few years ago in Lake Garda, Italy. My father is also a big fan of Eros Ramazzotti. He listened his music already in the 1980's before he became a big name. Toto Cutugno is not familiar to me, I've heard the name few times but that's it.
