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.
You Don't Have to Say You Love Me write their own lyric for an anti-love song to be called "I Don't Love You"; when that original idea proved unproductive it was adjusted first to "You Don't Love Me" and then "You Don't Have to Love Me" which was finalized as "You Don't Have to Say You Love Me" to fit the song's melody. Napier-Bell was later to title his first book (an autobiographical account of the British music scene of the 1960s) "You Don't Have to Say You Love Me" after the song. Springfield recorded her vocal the next day: unhappy with the acoustics in the recording booth
