The original treatment of the first TV-episode, written and conceived by Herman van Veen.
Legend has it, that he dictated the whole series in the car driving from one concert to the next.
From there it would come to us, Hans and I would work on the characters, props and settings, then a very nice Japanese gentleman, Mr. Akira Miyazake, would write the skripts. He had a biggest name in the production as a TV-writer , he was in his 70's and we got along very nicely, I liked him a lot. It was his first time as a writer for animation, so he would handle the characters as if they were real people, that's why he was hired for the job in the first place.
I would then go over the storyboards again, mostly to hear, that it was too late for changes, I would do additional characters, etc.
Once the production was up and running, they would produce one episode a week, even when the series was already on air.
They even dubbed 26 minutes of animation in 26 minutes. I saw that once, it was like an oldtime radioshow. Like Gerald McBoing Boing...
