 Scenes for the song "Hey You" were filmed, showing British police in  riot gear facing off against a mob. During editing,  Roger Waters (qv) and Alan Parker (I) (qv) watched a rough cut  of the film thus far. As they watched, they felt the film becoming  more and more depressing, and spur of the moment decided that "Hey  You" would be cut. The scene was also cut because it ran too long.  Years later, Waters looked for the footage, but believed it to be  lost. The scene was found in time for the production of the DVD in  1999 and used, though it was in poor condition; the color had  completely faded and editing marks were visible throughout the  whole sequence
