The first video has a great shot of the front row occupied by three Cobra's, in the second video you see the King Cobra. It's too bad there isn't car audio which would be preferable to the music. Hope this isn't a repost.

The Dick Guldstrand accident looks pretty vicious....I guess the later fix was the roller skate on the roll bar.....and the Bob and Allen show for 1963...."rubbing is racing."
