You Don't Have to Say You Love Me entitled "Jo no puc viure sense tu" was a 1965 single release for Renata. Pino Donaggio himself recorded a Spanish version of the song entitled "Yo que no vivo sin ti", which was remade in 1971 by Angélica María for her self-titled album and in 1987 by Luis Miguel on his album "Soy Como Quiero Ser", Miguel's version ranking at No.26 on the Hot Latin Tracks in "Billboard". Most international versions of the song were subsequent to Dusty Springfield's 1966 success with "You Don't Have to Say You Love Me" and reference that version's lyrics rather than the Italian original.
