re: Billy Elliot and the broadway changes!
Corey was flown over because Nick Twiney fractured his wrist at home literally days before he was due to do his first performance as Billy. They did a week or two with only three Billys but because of our child labour laws, it became necessary to bring an extra Billy over from London and Corey was chosen. Nick must be just about recovered (he got his plaster off on opening night - 13 December), so I presume Corey will be back in London shortly.
