Shot on Potsdamer Platz, the no man's land between East and West Germany, the producers didn't know if the area would be filled with mines - no one did. Before setting up, they did a sweep of the area and found a slew of munitions and a previously unknown Nazi, S.S. bunker, the very same as Hitler had lived his last days as seen in the movie "Der Untergang".
During the live TV transmission the second and third songs, "The Thin Ice" and "Another Brick in the Wall part I", were disrupted when a circuit breaker tripped. It was reset, but immediately tripped again. As part of the precautions against such events marring the video release of the concert not only was the previous day's full dress rehearsal filmed but the stage was also cleared (and as need be rebuilt) once the concert was over to allow further performances of any songs that had suffered from audio or video problems be re shot. Much of the footage of "The Thin Ice" and "Another Brick in the Wall part I", and some from "The Happiest Days Of Our Lives" used on the Video, Laserdisc and DVD releases is from these encore performances.
The performance of "Mother" used on the video, laserdisc and DVD releases was from the previous day's full dress rehearsal. The concert performance of this song, featuring Sinéad O'Connor and The Band, had been spoiled by technical difficulties rendering it unusable so as planned the song, and others that had suffered from technical problems, was to be performed once more straight after the concert itself had ended. However despite taking part in the encore performance of "The Tide Is Turning" Sinead O'Connor was nowhere to be found backstage, apparently having been offended by Waters' request that "If need be just mime". It is also noticeable during the video version of the song that several members of The Band are reading their parts from lyric sheets placed near their feet. It is doubtful they would have used such props at the concert itself.
