 Casablanca would assume responsibility for recording and distributing Summer's albums during the 1970s and also become one of the premier labels of that decade.While Casablanca would become the main label responsible for managing Summer, Groovy continued to distribute her work in the Netherlands and other labels were used to distribute her work in other countries, such as GTO in the United Kingdom, Atlantic in Germany and France, Polar in Sweden and Durium in Italy.From 1977's "Once Upon a Time..." album, Casablanca would take over the distribution of Summer's albums in most countries (though her releases in the Netherlands would be issued by Philips and [until 1978 and 1979 respectively] would continue to be issued by Atlantic in Germany and France).
