In order, from the Times, 24 January 1972 (two days after it happened):

From the Guardian, 1 March:

From the Times, 26 April (my fifth birthday):

And from the Times Diary column, 24 June:

(It is nice to see a reference to Nora Nicholson just after I watched a 1971 episode of Here Come The Double Deckers, "The Helping Hound", in which she plays a leading guest role.)
Anyway.Mr Martin's reported remarks in January seem extremely disingenuous. Having equipped the two women with faked press passes, did he imagine that they were just going to pull the Prime Minister aside in Strasbourg or Brussels, for a quick and friendly chat about Covent Garden, as a result of which he would see the error of his ways? I can't quite see it; in fact, I bet he bought the ink as well.
Google doesn't bring me very far, but does at least take me to three published books.
- Discipline or Corruption, mentioned by the Times columnist, is generally catalogued identifying Stanislavsky as the primary author (somewhat implausibly, given that he had been dead for three decades), and George Martin, Anna Darl, Karen Cooper, Susan Harris, and Jennifer Harris listed as contributors.
- Anna Darl is also the author of a 1969 work published by the Institute for Personal Development, with the resounding title System of Personal Development: Activium [sic] for the Exercise of the Brain and Development of the Mind.
- And in 1964, the Covent Garden Centre Ltd published a pamphlet with the title Covent Garden Centre: An Economic Project in the Public Interest.
I have ordered Discipline or Corruption, which sounds rather intriguing, and will report back. Thanks again to the person who supplied the clippings.
