With Mama in January 1967 , Dalida had success in France and Turkey , and was back on top of Italian charts later the same year . " Ciao amore , ciao " , written and composed by Tenco , was released alongside as they chose it for their competing song at Sanremo Music Festival . The festival premiered on 26 January and they both separately sang their own version . Under the influence of stage fright and alcohol , Tenco delivered a very bad interpretation while Dalida concluded the evening with ovation , but eventually they were eliminated in the first round . The following night ended tragically when Tenco was found dead by Dalida in their hotel room . It was reported that the suicide letter explained how he committed suicide due to elimination , as protest to hoax and bribed jury , but the major suspicion emerged how actually the mafia was involved . Although the public did not know anything about their relationship , the event greatly affected Dalida and the next concert in Boulogne-Billancourt scheduled for 31 January was cancelled . The following week on 7 February , she appeared on TV show '' Palmares des chansons '' dedicating her rendition of " Parlez moi de lui " to Tenco . Wearing the same dress she wore when she found his body , the performance was highly sentimental but she showed nothing of a verging depression . On 26 February , Dalida attempted to commit suicide , ended up in a hospital and spent five days in a coma . The truth broke out about her engagements with Tenco , leaving her worldwide public stunned . Her career was put on hiatus for three months
