While I was cleaning up my pile of old magazines, I came across an old UK issue of GamesTM and saw on the cover that Jazz1 was being featured in it's Retro section. So I decided to read the article again and found that it was a how/why sorta interview with CliffyB about the development of Jazz1.

And since he supplied the magazine with his highschool notebook sketches of 'Rambo Rabbit' and couldn't find these on the internet, I decided to scan the article and cut out the sketches:


So there you have it, I guess the birth of Jazz the way we know him today can't be traced back any further. I could upload the whole 4 page article if anyone's interested without caring about magazine scan legality.
