If it's anything like the other series don' they have 4 shows of 6 lads and lasses, choose the best two from each and then have some kind of wild card format for the final 4..
Or is it two shows of 12 (girls and boys) with erm.....Can't remember
Anyhow - I'll be keepin the powder dry until these live performances in front of a small audience that starts this Friday..
