His longtime cooperation and partnership with famous German rock singer Peter Maffay kept raising his popularity which he would campaign for social and humanitarian activities.

In 1964 he decided to make a living as a professional and gained attention in numerous Galas und TV-Shows, also in foreign German-speaking countries.

Lasting problems during live and studio work due to Alcohol and Hashish consume have been spread as the main reasons for breaking up the cooperation in 1984.

In 1989 he left his residence on East Frisian Island Borkum only for receiving the award "Artist of the year in Niedersachsen", a small city event in Northeim and a five-day-open-air festival in Bremen – The Breminale.

He broached the issues of air pollution, forest dieback or the use of nuclear energy – sometimes radically – long before those problems where picked out as a central theme in Germany and elsewhere.

He constantly supported Greenpeace and the German groups and initiatives Künstler für den Frieden, AGA Aktionsgemeinschaft Artenschutz and Nicaragua-Foundation of Dietmar Schönherr.
