If I no longer had you) is a 1965 Italian song composed by Franco Migliacci (lyrics) Luis Bacalov and Bruno Zambrini (music) and performed by Gianni Morandi.
The song was runner-up at the 1965 edition of the Cantagiro festival;[1] it was in the lead for all stages of the contest but was eventually overtaken by Rita Pavone with "Lui" in the final stage at Fiuggi,[2] in what became known as the "Fiuggi blitz".
[4] It has been described as "a non-obvious melody rich in bel canto reminiscences", which Morandi performed "with great naturalness and without overdoing it".
[1] The song was adapted into a musicarello film with the same title, directed by Ettore Maria Fizzarotti and starring the same Morandi and his future wife Laura Efrikian.
