This is a song by Angelo Branduardi, an Italian folk singer and composer who scored relevant success in Italy and European countries such as France, Germany, Belgium and the Netherlands.
Branduardi was born in Cuggiono, a small town in the province of Milan, but early moved with the family to Genoa. He was educated as a classical violinist in the local school of music. At the age of 18, he composed the music for the Confessioni di un malandrino (Hooligan's Confession) by Sergei Yesenin.
He is married to Luisa Zappa, who wrote the lyrics for many of his songs. They have two daughters, Sarah and Maddalena, both musicians.
