The Jam headline at The Arts Festival in Saddleworth/Oldham.
The gig was in a large marquee so the explosive effects were placed outside for safety reason and to compensate for the distance between the stage and explosives the pyrotechnics increased the charge. As the band climaxed their set with the A-P-O-C-A-L-Y-P-S-E – APOCALYPSE !! The surrounding area of Saddleworth was treated to an almighty explosive din causing numerous complaints and visits from the emergency services, fearing the worse.
