This was the main language of a jazz pop musician whose signature song calls his home city “a thousand colors, a thousand fears.” It’s not Spanish, but a quirky Guinness ad popularized Pérez Prado’s mambo version of a song in this language whose title means “boy” or “urchin.” A song (-5[1])in this language about an “evil woman” was first written on a cigarette pack by a comedian known by the mononym Totò. A 1956 (15[1])song in this language uses English phrases like (-5[1])“I love you,” “whiskey,” “soda,” (-5[1])and (-5[1])“rock ’n’ roll” to satirize its (15[1])speakers (-5[1])as wannabe (*) Americans. (10[1]-5[1])Elvis’s (-5[1])single “It’s Now or Never” was based on a song (10[1])in this language (10[1])whose title means “my sunshine.” Richard Strauss’s first tone poem (10[1])accidentally (10[1])plagiarized (10[1])a song in this language that celebrates a cable railway on a volcano. For 10 points, name this (10[2])language used in “Funiculì, Funiculà,” (-5[1])“’O Sole Mio,” and other songs from Campania. ■END■ (10[5])
