I studied in Central London and had the same experiences - doing the Pavement Tango with Sir Trevor McDonald, pressed up against Alice Beer (who was very small and probably still is) on a crowded Tube Train, sitting on the tube opposite PC Carver from The Bill, watching DLT being heckled by passers by on his way to the BBC, passing by both Armstrongs (ITN newsreaders) on New Cavendish Street, having to run out of the way of Mark Knopfler has he drove along Regent Street, seeing Derek Jameson and his Mrs doing a piece for camera outside the Beeb, spying Mike Read ("Mike Read, Mike Read, 275, 285 National Radio One...", not the "Riiiicky" one) driving into what is now Wogan House, watching Leticia Dean getting dropped off at her flat and then being admonished by the taxi driver as he passed for "ogling Sharon" (we weren't!) and bumping into Samantha Fox outside Tower Records on Piccadilly Circus. She was small too. Who else? Enoch Powell, The Queen Mum (in a cavalcade), I could go on, but had better not!
