This is another of those "I should know this," things, but I don't. More annoyingly, I can't seem to find the answer in any of the obvious places, and it should be easy.
I have seen a video clip of a helmetless Jacky Ickx and Derek Bell ascending the Goodwood hill in the 1975 Le Mans-winning Mirage GR8, with an accompanying interview with Lord March describing the efforts he'd made to attract Ickx to the event. He says this was Jacky's first appearance at the Festival.
I have shots of Ickx at Goodwood in 1999 in a Ferrari 512M, so if Lord March's comments are correct, this film predates that appearance. Please can anyone confirm what year the filmed Mirage demonstration took place, and - better still - does anyone have a decent photograph they could be willing to licence for the upcoming book?
Thanks again in anticipation of your help.
