Dalida and her brother Orlando were already planning for some time to form their own record house as a vehicle to release and to control her musical output. Dalida's last record released under Barclay label was "Concerto pour une voix", an EP released on 15 April 1970. On 1 July Dalida signed a contract International Shows, recently established by Orlando, making him one of only several independent producers of French show business. Their first record "Darla dirladada" was also the first success of a very long series. Already played on radios for a month, the Greek folklore song was released as single on 15 July. "Darla driladada" was an overnight hit, selling 75,000 copies within the first week and setting a record for largest weekly sales in France. The song became Dalida's another tube de l'été, staying three weeks atop of French sales charts during summer and gaining gold certification in a month. Soon after, Dalida released her second record under her new label; "Ils ont changé ma chanson", a cover of "What Have They Done to My Song Ma", reflecting a drastic change of her repertoire in past years. It was a moderate sales success, but it won her second Radio Luxembourg award. That was followed with "Pour qui pour quoi", her last record in EP format, and "Ils ont changé ma chanson", the first album issued under International Show.
