I downloaded this the other day and had a look. I enjoyed it, but I agree that the newer stuff about the football stars and Tiger Woods was unnecessary. Those parts seemed sort of rushed and pieced together rather poorly. I'm not sure if they were trying to make a commentary on Modern Media Coverage and Modern Morals, or just have a simple "Look how much things have changed moment", but these portions of the program didn't add anything to the show.
One of the big revelations from Alistair Caldwell was that Hunt did not want to race at Fuji in 1976, and that he was only coerced otherwise by the team and an unknown Japanese woman. According to author Tom Rubython, Patrick Head stumbled upon this woman servicing James in an empty garage shortly before the race start in order to ease the mounting tension. The rest, as they say, is history.
