Yep Keith I stand corrected, it was 79 GP, with Silverstone only 30 Miles up the road we use to go to most of the GP's back then, especially as there were more GP race classes to watch. And as you say David Essex sneaked out onto track with it.
Suprised I remember much about those GPs at all considering the parties we had on the campsite on the Saturday evenings after doing the bear run down to Brackley.. I think it was 79 when 7 of us fell off a RD350B in front of the Stowe grandstand to everyones ammusement.
Those were the days
