Singers/Choirs/Dance acts really aren't my bag, but I love a bit of variety act.
As soon as he walked on stage looking like Robin Williams from Good Will Hunting, I knew he was gonna be good, and the first 'stumble' up the ladder confirmed it.
I long ago, gave up on the idea that these people are randoms, who have been mucking about in their bedrooms or gardens for years, and try a shot at the big time.***
So I treat the show a bit like an actual Royal Variety Performance, and enjoy the acts (or not) on face value.
Him I really liked, and would watch him again no question.
***The only time I was a bit aggrieved was when Stevie Starr (I'm sure that was his name), the guy who swallowed things, was on a few years back. In his time he was quite big and well known.
I thought the producers were taking the piss a bit then.
