Hmm have been thinking about this and for me there is no comparison between Jimmy Savile and Elvis...
But it is a grey area in the 'Elvis' situation (in my head anyway) which I'm just not sure about. JS - no question, was a sexual predator & crimes were committed. Evil, horrible man.
Elvis met Priscilla when she was 14 (I don't know of the 13 year old, although I realise a few months doesn't make much difference). In my mind it was a very different situation because, rightly or wrongly, they fell in love, she was a willing participant, they eventually married and had a legitimate relationship, etc. I do think their relationship was wrong when they met and Priscilla was underage - and it seems she was completely unprotected by those around her, from getting into a relationship she was clearly (and legally?) too young to cope with. And what that says about Elvis I don't know.
But I don't think it makes him a paedophile. Maybe it does, legally (although I don't know what the legal age was in that part of the US..).
But JS was clearly a paedophile.
In my mind there is a big difference between the two situations. Neither situation was right (morally, anyway), but I think there needs to be a distinction between somebody like JS and somebody like Elvis.
