Well, Ruggero is standing here next to Marino. Ruggero recorded so many song in the early period that a correct name of the group could as well be Ruggero Cori and the Marinis...
Marino sung many hits and obviously was the head of the group but he is Ruggero who perhaps was the heart of the group.
Io mammeta e tu Guaglione and Sophia are just some of the examples of his fine art.
