The site has been hosed by the 'Cox Effect'. I can't get to it now either. I am also hampered by being away from anything decent web connection wise thus weekend.
Basically, it seems that people were up to no good a generation before Savile, including Uncle Mack. However it seems that attitudes were very different, and it was not seen as 'wrong' in the sense that it is today.
It also says that there were a lot of problem people working in entertainment, or rather people with problems. I can't help thinking that other TV channels would have the same problems as the BBC. There are names mentioned, including Benny Hill (no direct allegations against him there). Conclusions can be drawn. History will determine how right yours are.
And if there are problems at the BBC during the times of Muffin the Mule, then I guess that theatre, music hall, and other places of entertainment will also be venues for such goings on.
It's quite a long article and covers much ground. Well worth having a read when it's back.
