I came across a book I bought as a child The December Rose. I loved the series. Around that time I recall it was quite standard for the BBC to produce a brilliant series for children.
Ones I can recall (though not sure if they were all bbc) are:
December Rose (obviously!)
Moondial
Box of Delights
The Lion, the Witch and the Wardrode
There were more I'm sure can anyone remember other ones (obviously different ages will have different memories!). More impressively can anyone recall what day they were broadcast on?
Moondial was weekday, during children's tv hours I think, and Box of Delights on Sunday evening?
