I just received this link from AutoWeek. It's an on-board with Mike Hawthorn in a D-Jag, driving around the Le Mans circuit prior to the 1957 race. It is wonderful!
Throughout the video, Hawthorn gives a running commentary from behind the wheel, casually discussing the local traffic, course improvements and particularly challenging segments of the circuit -- never missing a beat as he pushes his streamlined Jag through curves and down straights. I love his comments about the bicyclists on the course at the start of the Mulsanne!
Check out the high-tech camera and microphone set-up. That's what a Go-Pro Hero would have looked like halfway through the last century.
