Thirdman-
yup, your supposition is correct - although this Forum isn't perhaps the place to conduct such a flirtation; my fault for providing perhaps TMI; anyway, I was in 8ABi with the legendary Sid Pask (other mentees Jonathan Miller, Oliver Sacks etc etc) and what HM was recoiling from was a writhing mass of nematodes on a projecting microscope screen that I'd mischievously set up in the hope of just such a reaction - the DofE was fascinated.

I've identified a number of other Listener pseudos accidentally through outside conversations - one, who's now my Listener buddy, when I won a prize - John Green publishes the winners' names in 'clear' - I'd known her unsuspectingly for years.
Jazzgirl twigged my real life identity years ago through mention of the instrument on which and where I'd played Jazz - bloody clever!
