Hi Al
Apologies for any confusion - I wasn't for a moment suggesting that Jacob is rubbish (or in any way afflicted for that matter), far from it. And sorry if this has ended up as a bit of a thread hijack (unintended).
My comment was in relation to those early round auditions where, amongst all the talent, are some people with a glaring misapprehension about their singing talents. It's pretty clear to me that they are not fully socially aware and I think the shows shamelessly use (and therefore abuse) these people and poke fun at them.
One famous case, that totally bucks the trend, is
the first appearance of Susan Boyle on Britain's Got Talent (but I'll include it here anyhow as it still illustrates my main point). You can see and feel the preconceptions from the audience and judges on the show as she stood on the stage for the first time. But for the fact that she has this amazing voice, I think she would have been ripped apart by the judges / audience. After losing the final she spent time recovering in a private hospital and in later years she was diagnosed with Asperger's.
British comedian, Jo Brand (a former mental health nurse),
has this to say on the matter.
