During the production of the documentary various recordings were made: tapes at001-at010 are master copies of the sound track of the film made for security purposes; tapes at011-at013 are lower speed dubbed copies of the sound track master copies; the remainder of the tapes are raw and dubbed recordings that were in part or as a whole used in the productions. Of particular interest are tapes at019-at023 because they are recording of Snow and the editors review the film footage during the editing process. They discuss ideas for the script and Snow relates information and memories stirred by the images.
