BigT - about 85 time I was on the RAF TV Course at Newton. Each of us studes was given an "unknown", surprise topic for an interview. Mine was based on press confusion between GLCM vehicles and mobile radars (I was stationed at Neatishead). One of my colleagues was give a question based on the relationship you mentioned, which caused something of a stir, as the stude concerned (a) had been best man at ES's wedding, and (b) knew nothing of the "news item" - in all senses.
