Caffetto made his debut at a very young age around 1890 as a comprimario.
He almost immediately sang important roles: Des Grieux, Siegmund, Ernani, Roberto, Pollione, Turiddu, Radames, Enzo, ...
Outside Italy, he sang in Philadelphia (1902), Bucharest (1903), Malaga (1905),...
After Malaga in 1905, Roberto Marcocci could not find more information on him in Italian Theatrical Newspapers.
It's possible that he was active in England in his last year.
