Whilst we're on the subject of show-men of that era, has anyone seen the Video/DVD "Devil at your heels"? The story of Kenny Carter "The Mad Canadian"?
The Late Show on the ABC resurrected this gem in the 90's. A serious documentary (you may think otherwise), it's this guy whose been jumping heaps of shit cars over two or three other heaps of shit cars for a few years and then gets this brainstorm to jump a rocket-powered (rockets and rocket fuel must have been cheap in those days!) car, one mile, from Canada to The US. Over the coarse of about five years he tries everything in his powers to get out of it 'cause you can see he knows he's gunna kill himself! A heart warming and touching doco, you can't help but wanna strap Kenny in and light the fuse yourself!
I wont spoil the ending, but it's a SCREAM!!!
