Pertini will be cremated in Rome on Monday morning and his ashes taken on the presidential plane to his birthplace outside Savona, near Genoa, for a private funeral service, the ANSA news agency reported.
Giampiero Cantoni was named chairman of the state-owned Banca Nazionale del Lavoro and Paolo Savona will be director-general, the government said.
He wrote hundreds of songs and was the founder in 1941 of Quartetto Cetra, which launched such favorites as "In the Old Farm" and "Box at La Scala." Other members of the quartet were Lucia Mannucci, Virgilio Savona and Felice Chiusano.
