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.
Don't Say You Love Me (M2M song) interview, M2M replied "the "Pokémon" people didn't find it appropriate to have kissing in the lyrics, because it was for younger kids. We think [the lyric change] was stupid. The original version is on ["Shades of Purple"], and that's the one we wanted to go with." M2M had not heard of "Pokémon" until the song was chosen for the soundtrack, as the franchise was not yet popular in Norway. "Don't Say You Love Me" appeared in "The List", an episode in the TV series "Felicity" that aired in the US on 3 October 1999 and reached an audience of 5million
