Strictly Technicolor X Factor

Sky One's new big event show, Hairspray: The School Musical, manages the rare feat of piggybacking on two of the big TV trends at the same time. In case you don't know it, Hairspray: The School Musical - a working title, thank goodness - will follow a UK school's attempt to put on a West End quality musical. So it's half Any Dream Will Do - or any of the other of those Andrew Lloyd Webber shows on BBC1 on a Saturday night - and half Disney's High School Musical. Ingenious! If only it were presented by Ant and Dec, featured a judge who could travel through time and, er ... had Sir Alan Sugar firing various members of the school staff, it would have all five ingredients necessary for a hit TV show.
