1980's musical group "Men Without Hats"
The group scored with a top 20 hit "Pop Goes the World" later in 1997, however none of their following albums topped the success of their first. The group split up in 1992. After attempts at solo careers, Stephan and Ivan got together for the last time in 2003 to release their final album "No Hats Beyond This Point".
