Sorry to hear of his passing. I believe Speedvision is the channel where his most memorable work was done. He was great on all the shows.
Speed Channel was a fox abomination that tried to force Nascar on car nuts who prefer to turn left AND right.
Legends of Motorsport is still my all-time favorite documentary series. Looked forward to every new episode. In particular because it gave us automotive history in a time right before the internet first blew up.
