I heard a similar story to the KISS episode. Apparently at an Earth,Wind and Fire concert, the band abruptly stopped performing and asked all JW's to leave the venue because they were blocking the demonic spirit from possessing the crowd.
Of course all of the DUBs in attendance ran out of the stadium and vowed never to listen to EW&F's music again. The elders made sure to repeat this story every chance they got to the congo's teenagers.
