WTF is Lloyd Webber going on about with the group number?! The two I'd have picked out as horrible were Niamh and Jessie, but he said they were the best.
Am still not getting it with Niamh. She's got a shrill, shouty voice.
And Jessie's mouth... she's got to learn not to clamp her top and bottom teeth together when she sings. It's hideous.
