This clip of 1966 LeMans highlights, which looks to have been pulled from an episode of Legends of Motorsport (where’s a Legends of Motorsport DVD box set, Speed Channel?) has some very nice details, including voice over narration from Graham Hill, Bruce McLaren, John Surtees, and Carroll Shelby.
The absolute highlight, though, has to be the footage of the go-kart racing on the carnival midway starting about 3.5 minutes in. Excellent footage of some 9 or 10 year old boys sprinting and leaping into their sportscar bodied karts complete with bucket crash helmets and miniature Dunlop blues. The voice over by John Wyer, while they race is describing the race at LeMans, but meshes very well with the karting action. Great stuff.
