That was cool to watch. Another thanks for posting it.
Back in the primitive days when I was a kid, there was no motorcycle racing on network TV where I lived. Maybe, just maybe, once a year or so they might feature some kind of race on ABC's Wide World Of Sports.
My older brother had a 45rpm record that was nothing but the sounds of motorcycle engines at the Isle Of Man race. I'd forgotten about that for 40 years or so until you posted this. I can still see the picture of the motorcycle on the paper sleeve that held the record.
