These concerts took place less than two months following the conclusion of Led Zeppelin 's 1975 North American tour . The whole of the band 's 40-ton stage and light show was airlifted from America for the concerts . A huge Eidophor screen which showed the action as it was being filmed was also erected above the stage , at a cost of £ 10,000 . This is thought to be one of the first occasions when such a device was used for a rock show in England . It was said that an entire city could be lit by the energy spent in a single concert . Three days of rehearsals took place in order to fix every possible detail or PA problem . The sound at the concerts was managed by Showco
