Meanwhile, the fan base of the band was growing as was the number of performance dates. In 1983, Robert Prskalowicz replaced Hans Hauptmann on bass and this group became the best-known Cacumen formation, but when they signed with BMG, the group had had a total make-over. Prskalowicz and Hans Forstner were no longer with the group as of March 1985. They departed because they could not commit to the group full-time and were replaced with Joerg Deisinger on bass, previously from Rascal and Dynasty, while Dominik Hülshorst from Darxon became the new drummer. The band updated also their image, donning the standard look of an 80s hard rock group. Finally, the company requested a name change, as they found Cacumen was too hard for the average customer to pronounce and not a very marketable name. After a brain storming session, the new name selected was Bonfire, which came into effect in May 1986.
