KOLORS and the gig in Köln

[Wouter Vuijk]

The Rockpalast archives mentions for the line-up Duban Laverde (aka Spartacus R) as bass player. I also have an audio where the presenter gives a short history of Peter Green and finishes his comments with the line-up. He too presents Duban Laverde as the bass player.
However, since Kolors has some Osibisa roots, I wonder if the bass player might have been Spartacus R from Osibisa, whose real name was Roy Bedeau. Could it have been that Spartacus R was the bass player and the Rockpalast organisation wasn't aware of two of them and assumed it must have been Duban Laverde??????
