Full lyric line: Io Che Non Vivo Piu D'un Ora Senza Te; I Can't Take It More Than An Hour Without You. San Remo song that year. Songs are presented by two different performers on that festival; helps judge the song, not the singer. The second version of Io Che Non Vivo was by Jody Miller. That second version didn't have to be in Italian.
Jody Miller [second San Remo version]
Los Mustang [as Yo Que No Vivo Sin Ti]
Dusty Springfield [n°1 UK as You Don't Have To Say You Love Me, new words by Simon Napier-Bell and Vicky Wickham, from now on her manager and partner]
Jackie DeShannon [idem]
Guys & Dolls [all as You Don't Have To Say You Love Me]
André Hazes [as Geloof Me and in '86 as Io Che Non Vivo]
That's the same Pino Donaggio who scored horror movie Carrie.
