If Jimmy Savile was a UK/US 1970's / 1980's rock star or indeed politician would we be at all bothered by these accusations?
I only ask as many of them (without naming names for libel purposes) enjoyed the company of "younger women" and due to their living reputation nothing has ever been done!
The cynic in me thinks that while rock stars of a different era got away with this sort of thing, their popularity has protected them. If you produce good music that people still enjoy and radio stations still play, it's rather inconvenient to start demonising them with child abuse allegations.
Gary Glitter was considered a bit naff even before his exploits came out so that was no loss to the music industry. Jimmy Savile also fits the bill. An eccentric and slightly weird character that fits in with the "Child Catcher" stereotype idea of someone who harms children.
That said, based on what I've seen and heard I'm pretty sure Savile did at least some of what it being claimed. There are too many stories coming out. Plus the latest allegations of roaming around hospital corridors, preying on sick kids takes it to a whole new level.
