Brian... No news on JK or Ronnie Radar except I've no reason to doubt that they're still around. "Ronie radar" is a "name" he objected to even though it originated through his own fault. He was doing GMC one day with it right round his neck and he stood up and said "My forte is radar"!
One day in the old 6th floor APC Room, Tels said they wanted to do something to the No.2 Director console. The only person who wasn't told was Ron, who had a penchant for leaning on his elbows with his chair pushed right back and his head almost touching the screen. Tels duly arrived and slowly pulled the radar display out.... Ron duly edged forward.... Eventually, a couple of people grabbed him before he disappeared into the gaping hole like a certain 1-11 skipper.
JK... I could talk all night, but won't!
