I know have the full 4.8 meg wav file on my site thanks to Dave who just sent me the original version.
Wayne Snell of Toronto's Ryerson Polytechnical University created the file but his site no longer exists so I hope he is happy people still enjoy his work. I got a real charge out hearing it again. It is very clever in the way he develops the ideas in it.
