I have a theory about this - some are part of the New Establishment. If so, their public disgrace incriminates and reflects poorly on the general public - it makes them look foolish and whole swathes of their upbringing have to be deleted. History has to be rewritten, almost. The State will want to avoid that.
It's easy enough to eliminate Jimmy Savile because he fronted some TV shows, he didn't create anything, no records or movies. Ditto Rolf Harris really.
Ironically, the likes of Sir Cliff Richard, Freddie Starr and Paul Gambaccuni got it in the neck because they are Old Establishment. They hadn't done anything wrong, nor Leon Britton or Field Marshall Lord Bramall, but the police went after them - in my opinion as a misdirection tactic to distract from the number of grooming gangs, rings really in various local authorities, almost certainly overseen by them and the police. Okay, the police might have found something - they were on a fishing expedition - but really they could be thrown under a bus. Sir Cliff's records weren't being played much, he hadn't done much to keep himself relevant, he avoids interviews with the music press. If he's really been part of a paedophile ring with extensive links I'd never expect the Met to go after him - they had no form on this. They'd cover it up, more likely. Dame Cressida Dick sat on a file linking serial killer Levi Bellfield to care homes, and Lambeth paedophile activity in its care homes was suppressed for decades. Again, links between Prince Andrew and Epstein were coming to light around this time, so they may have been into misdirection.
Anyway, the surviving Beatles, Stones, Who, Bowie - they were never likely to go after them, whether the allegations are fictional or not. Others in the bracket will be Take That, Duran Duran, Spandau Ballet. Ironically these are the New Establishment - you don't take them down. They enjoy the privileges that used to be afforded MPs, Royals, the upper classes and so on. While some members of the Royal Family like Prince Andrew, they're Old Establishment and generally seen as fair game.
