Biography

He wrote the music for the opening and closing credits on the Japanese cartoon adaption of the 1990 TV series Moomin.

In 1978 he was a guest in the Flemish talk show Noord-Zuid by Mies Bouwman and Johan Anthierens, who treated him unfairly. Anthierens in particular criticized his commercial attitude and put forward a rumor that Peyo had not yet received any copyrights related to 't Smurfenlied. The singer felt so offended by Anthierens' criticism that he left the studio indignant. As a result, Peyo reported that there was no financial dispute.

As Lord Wanhoop (Despair), he recorded a number of "oblique" and ambiguous songs such as Herbalist, Lily Marleen, Tonia and In the Bath with Violetta (chorus: "Not too hot, not too cold").

Another hit was We are the Wuppies. Albert Heijn and Johan Vlemmix, who had a Wuppie promotion and Wuppie song around the 2006 World Cup, fought a dispute about this together in court. Vlemmix had to withdraw his single.

Kartner himself calculated that about two billion people must know him by now.
