Lucio Dalla wrote “Caruso” in 1986 after staying in the same hotel room in Sorrento where the famous tenor Enrico Caruso spent his last days in 1921. The song imagines the old singer at night, looking out at the Gulf of Naples, singing to a young woman, feeling life slipping away and love still burning.
The chorus is in Neapolitan — the language of Caruso's city — and it's one of the most famous lines in Italian song. Luciano Pavarotti and Andrea Bocelli made it world-famous, and it's been recorded hundreds of times.
It's B2: the verses are poetic and the images layered (the sea, the lights, the boats, a life ending). Learn the chorus first; it's the heart of the song.
