While Dalida was professionally very successful, her private life was marred by a series of failed relationships and personal problems. In January 1967, she took part in the Sanremo Festival with her new lover, Italian singer, songwriter, and actor Luigi Tenco. The song he presented was "Ciao amore ciao" ("Bye Love, Bye"), which he sang together with Dalida but Tenco failed despite Dalida's performance. Tenco died by suicide on 27 January 1967, after learning that his song had been eliminated from the final competition. Tenco was found by Dalida in his hotel room with a bullet wound in his left temple and a note announcing that his gesture was against the jury and public's choices during the competition. Prior to Tenco's suicide, Dalida and he had become engaged. One month later, Dalida attempted to take her life by drug overdose at the hotel in Paris. She spent five days in a coma and several months convalescing. Dalida returned to the stage the following October.
