Childrens audiodrama cassettes - Spectacular incidental music of your childhood

As a child I was infatuated with audio drama cassettes and records. I had loads of all kinds of stories, fairytales and crime series. The ones that stood out the most were "Die drei ???" aka "The Three Investigators". I heard these adventures literally everyday and sucked it up completely. (In fact there's a huge fanbase of adult listeners in germany to this day.)
What always caught the ear listening to these tapes or records was the rather unusual incedental music which till this day has encapsulated the sentiments of being a child excited by the adventures of Justus Jonas (aka Jupiter Jones), Peter Shaw and Bob Andrews.
The soundtrack was created by Carsten Bohn - founder and drummer of the progressive rock band "Frumpy" - and his later group "Bandstand". I like how the typical sounds of fusion-jazz and prog sneaked in my untrained ears just naturally and I still like the music from the series.
