It's nice to hear your thoughts SimbaY2K+4 - there aren't many people who like the Olivers on this forum! I personally find them much more interesting than the Nancys who are rather boring at the moment. I wish they show more of them - maybe give them two songs per week, split them up into two groups of 6 so that they'll each get a longer solo line? I thought it a bit pointless them singing in pairs last week because we couldn't tell their individual strengths.
I agree that Alex and Jonny look similar - at the beginning I couldn't tell them apart. That's why I think CM will only put through one or the other. At the moment I'm leaning towards Alex actually, although Jonny was my initial favourite, because he's younger (Jonny's 13 and his voice will break soon), his vocals are stronger and he looks more like an Oliver to me (Jonny looks more like a Billy Elliot). I agree that he appears more reserved/shy whatever on stage though and that's why he doesn't stand out as much.
Gwion is like cuteness personified - but I think the majority of his charisma comes from his Welsh accent. If the producers make him get rid of it I think he'd be a lot more ordinary. Chester I really really like and can't find any faults with him at all; easily the strongest/most suited out of the four chosen. I was a bit bewildered by Arthur's choice but he is good for his age. Kwayedza I've mentioned before - he sounds too grown-up already and sounds more like an R&B singer than musical theatre! That kid is seriously good, though. I *loved* "I'll be there".
It seems a lot people have warmed to Gareth recently - I thought he was really really good in "I whistle a happy tune" and in the VT he comes across as a really down-to-earth kind of lad, not at all posh. Plus he's Irish - I'm a sucker for Irish accents! I hope he goes through. I also really liked Harry last weekend; his acting is top notch and he appears really confident on stage. I'm also warming to Laurence. The VT clip of him singing (about 4 words, admittedly) really made me notice him and he's got an Oliver look too. I think he's got more to give! He's got the worst colour scarf though - beige?? (actually, the scarf colours are crap. Why on earth give three Olivers red scarves??)
I'm afraid I've not taken to Jordan at all, and I don't think Oliver is right for him. He's a bit too.... manic - Oliver needs to be a bit more vulnerable and have a kind of dark, sensitive side (or maybe just generally being a bit of a wuss

) and I think Jordan's more suited to a Dodger-type character. Similarly, Sam just doesn't scream "Oliver" to me though he's very good. And Joseph is.... just Joseph.
Ideally I want Alex, Jonny, Harry and Gareth/Laurence through, with Chester + 2 of them winning the role!
Either way, I think ALL of them have talent, not the least for having the guts to perform to millions of people behind a TV and respect them all for that. Sometimes they give the Nancys a run for their money! When I was 11 I think I spent the whole day playing the Sims.
