Great! I reckon you should overdub the crackly sound with a nice chilled track from Jon Brooks or something? :)
We used to go on holiday to Butlins in the 1970's. Without any nostalgic exaggeration, I have to say they were probably the best holidays I've ever been on.
We also used to go to Butlins every year when I was a kid, and I find this footage very powerful; its fragmentary quality comes extremely close to being like my own memories of these holidays. I love the sound of the projector on this too.
Someone should loop that projector sound and do something with it. Bagsy it's me.
