Dalida debuted 1960 with "T'aimer follement", a chart topper in France and Belgium in February. Then she embarked upon her first world tour and reached top of the charts again, with "Romantica" in April. The third release of the year "Les enfants du Pirée" brought Dalida huge commercial success becoming her second big international hit after "Am Tag als der Regen kam". It reached top two in six European countries and Canada, topping charts in three of them. After its debut atop of French charts in June 1960, where it remained for 20 weeks, it became the first song by a French singer to sell over one million copies internationally, and the tube de l'été expression was invented after it. Dalida eventually recorded it in five different languages and made a video for TV emission "Toute la chanson". With a harbor theme, showing Dalida singing and lying on a fishing net and artificial wind blowing, it made journalist Jacques Chancel call it; "the first video in France that really made a shift from the era of outdated videos".
