If you like Children of the Stones (1977), you'll probably enjoy Stones by Malcolm Bradbury and Christopher Bigsby (writing as "Malcolm Christopher"), which was broadcast the previous year, and is a kind of compendium of mid-'70s tropes around prehistoric stones, tourism as preserver-destroyer, and of course possessed children. I found it because I remembered reading a story in which there was a proposal to move Stonehenge to Hyde Park, and Dr Google led me thither in my search; but whether a) the story was a version of this TV play, or b) vice versa or c) I misremembered the medium in which I'd encountered it or d) two different writers had the same not-entirely-remarkable idea for a story, I don't know.

There was so much of this kind of thing in the 1970s, I suppose it's no wonder I turned out as I did.
