The song is sometimes confused with the song Che sar??,[5] released by Jos?? Feliciano, first in Italian in 1971, then in Spanish as Qu?? Ser??, but the two songs have nothing in common except the similarity of their titles and the general theme of concern about the future. (Che sar?? was written by two Italians, Jimmy Fontana (born Enrico Sbriccoli) and Franco Migliacci.)
