He could have fathered children without ever having to have physical contact with the mother.
Paedophiles, whether famous, like Michael Jackson and Jimmy Saville or your everyday neighbourhood variety, are very careful and clever in who they target, checking out not just the child but the whole family set up. Most of his targets came from unsophisticated families, not on the bread line, but not far above and he love bombed the whole family and dazzled them with his wealth.
I find it difficult to believe the parents could have been so unaware, but I think they were. Frankly I wouldn't have let my children anywhere near a man like him, like Saville, he always struck me as being a very peculiar and unsavoury person.
I'm amazed that there are people on here who don't feel that Michael Jackson was an amazing artist, both musically and in dance
As for his music, when he died and they kept playing his music on the radio, I recognised none of it and none of it stayed in my mind. I could say the same as the above about Beethoven or Mozart, but I realise that one person's amazing music is another persons noise.
