Interesting to hear where the clips came from. I tried to find Disneyland Source, but the site seems to be 'mostly dead' - even using the wayback machine, there's not much of it left archived. The good news, is that is lives on in its successor www.visionsfantastic.com and bizarrely on there, is a WMV version of the mpg file i uploaded, as well a smaller differently edited version using the same footage, even down to the overloud distorted audio.
Was hoping they might have more info on the ride on their site, but they only seem to have one page, with a single image devoted to it, aside from the video clips.
If anyone wants the clips from the visions fantastic site, they're free to download from the site, but you have to register (for free) to access them.
