But if your question was about opera, at least at the Met, you could check out a score at the Lincoln Center library, and get one of the obstructed-view seats in the nosebleeds where the Juilliard students sit at desks with lights. A study experience.
On the other hand, Caruso wasn't alone in singing Neopolitan pop songs for his encores: "O Sole Mio," (Di Capua) and the English language "Parted" (Tosti), for example. Opera was a popular tradition in Italy, and only since made into some high art experience where you have to have some toilet paper stuck to your high-heels in order to enjoy it.
Best,
Charles
