There was a meeting of minds which eventually led to both of them playing in the first incarnation of the Gereformeerde Blues Band. A short while later, André left to forge a solo career as Koos Kombuis, while Ralph, by then known as Johannes Kerkorrel, went on to record the seminal Eet Kreef album with the remaining members of the GBB. Both artists featured on the Voëlvry compilation, which came out around this time.|deadurl=yes|archiveurl=https://web.archive.org/web/20131029204043/http://www.shifty.co.za/shif4.html|archivedate=29 October 2013|df=}}

This time the insurrection was a musical one, with the GBB as rock & roll outlaws slinging guitars and stinging criticism against the laager mentality of volks kultuur and the apartheid way of life. Moving conventional rock into the realm of political theatre and satire as successfully as they did proved that if the GBB were to be seen as cultural upstarts, they were upstarts with a vision both innovative and lucid that could not be ignored.}}
