I really don't think they should be putting that kid out there as a novelty act. I mean he's playing with adults, why not just get an adult to play with them. Probably he/she'd be better at it and better able to handle those stresses.
On the other hand I do think it's amazing what some teens can do, such as
Anton Oparin. But even there it's not original music being put out, although playing Paganini isn't worse than what a virtuoso violinist, of many ages would do...
I'd go, for the most part with what Satch says:
http://www.youtube.com/watch?v=dwX2papAyVk"Everybody who's talented shows talent at a very early age....But the kid's soul and their heart can be broken so easily.."
"..To subject a twelve year old to that would be pretty criminal.."etc.
