Original sentence: Angry concert goers have demanded refunds in their hundreds.Campbell had in fact been totally innocent and as the hate campaign began to get out of control his management jointly with the Human League and Go West issued a press release denouncing Signal 1 Radio for  the concert organisation and exonerating Campbell.Signal 1 radio was responsible for the '25th Anniversary' concert on 13/09/08 at Trentham Gardens where it was reported the audience were kept waiting in a holding area for 4 hours after the gates were supposed to open with no facilities or information.Subsequent disinformation provided by Signal FM staff on the ground to prevent crowd disorder, falsely accused support act Ali Campbell of causing the delays by his alleged prima-donna behaviour.The sound system apparently failed to work properly and the head line band The Human League had their set cut by two thirds causing lead singer Phil Oakey to apologise to the audience for, in his words “the shambles".They are also are being investigated by trading standards for breeching the UK’s Goods and Services Act.This then caused a hate campaign to be directed against Campbell by Human League and Go West fans who incorrectly blamed him for their bands being treated badly.UTV have refused to do so and are being pursued through the UK civil courts
