Well, I don't know if I'm on the right track or not, but Mike D'Abo claimed his name was Jack, Gary Glitter could be the disgraced pop star. Mick Moody, legendary guitarist from Teesside, played on albums by both of them. Are we looking for a performer who was a Mormon, too, say an Osmond? If so, that's just too "mainstream" for me, I'm glad to say!
