WOW! That is amazing! Cine footage of those days must be a rarity! Going back even further, when I was a yoof (please- no 'Before the war' jokes!) no scooter kids took a camera out with them! They were big bulky things (the cameras, not the kids! Though come to think of it, some of the guys were as well!) and usually they belonged to your parents! Also, as a sixteen year old on six or eight quid a week, these was no spare cash to spend on boring things like getting films developed! Consequently, rather sadly, I have no pics of me and my scoots back in the sixties!
Of course, nowadays in the digital age, everybody has a camera of some sort on them, and captured images are often regarded as throw away items, usually ending up in the recycle bin!
You try telling that to the young people of today- will they beleive you?? No!
