I came across a reference to a BBC Special in 1973 where Science correspondent James Burke carried out an experiment to test the Stone Tape Theory at Corfe Castle.
I remember watching James Burke's, 'Connections' series.
If we are referring to his 1973 investigation re, the, 'Stone Tape Theory', the earliest mention I can find of same is a 1972 BBC broadcast of Nigel Keane's science fiction play, entitled, 'The Stone Tape'.
Quoting Wikipedia:
"Contemporarily, the concept was popularized by a 1972 Christmas ghost story called The Stone Tape, produced by the BBC. Following the play's popularity, the idea and the term "stone tape" were retrospectively and inaccurately attributed to the British archaeologist turned parapsychologist T. C. Lethbridge, who believed that ghosts were not spirits of the deceased, but were simply non-interactive recordings similar to a movie".

As likewise with research endeavours of others, I can't locate online availability of the James Burke episode.
However, if the following is new background material, it might be of interest:

Further resultant of your interesting question, is the discovery we can watch our inaugural 1972 BBC Christmas ghost story on YouTube:
I have only had time to view the first couple of minutes so far and those who are also of a more mature vintage, will instantly recognise it's just so early 1970s!
Most certainly keeping this aside until an impending weekend evening, with unquestionable justification for an especially fine wine.
Perchance someone knowledgeable could suggest a befitting, 1972 accompaniment?
Although briefly viewed, my first thought was how reminiscent of Quatermass.
At that point, I did not realise this was also a creaton of Nigel Kneale.
