Eddi (Edzard) joined an 18-month alternative service for conscientious objectors in Brussels, which left the group as a quartet.

In April 1995, Ferenc Husta joined the group as the bass voice, replacing Christoph Tettinger, who could no longer sing for professional reasons.

In 1997, the Wise Guys turned professional, and released their third album Alles im grünen Bereich, produced by Uwe Baltrusch.

The usual tours were supplemented by big events such as "Tanzbrunnen", "Totalnacht", and "Spezialnacht", festivals taking place in Cologne.

"Zwei Welten" was also released as a two-disc package with two bonus tracks in December 2012, which brought them to their fifth gold record.
