As far as I'm aware there are at least 7 different versions (being they showed different kids). There were 3 for the U.S., 2 for the U.K., and 1 for Australia. I've also seen one with the second chorus of the children removed (with just the band playing).
By the original are referring to the "full length" one which includes the drawing of the missing girl who ran away 110x? There is also a quote and a speech by Dave at the end saying "If you've seen one of these kids, or you are one of them. Please call this number..." (with the number on the bottom of the screen). These parts were cut out due to time restrictions on music stations since the song isn't played during those parts.
I assume this is the one you probably mean by original?
If so, it was available on Yahoo at one point in time, but the closest I can find right now is what I think unfortunately took its place (judging by the title of the movie... it just includes the ending quote):
"In every child who is born... the potentiality of the human race is born again".http://video.yahoo.com/watch/2031843/v2162953
If you are referring to another version than the one(s) I mentioned, do you think you could be a little bit more specific?
