The Spice Girls are ready for their big West End first night. The women behind Girl Power will all be at the world premiere of Viva Forever which, I can reveal, will open at the Piccadilly Theatre in December, well before Christmas.Ghost The Musical, which is currently running at the Piccadilly, will close in the autumn.Based on the Oscar-winning movie that starred Patrick Swayze, Demi Moore and Whoopi Goldberg, Ghost has some terrific moments but, clearly, not enough of them to draw the kind of audiences that will keep the show running.The Spice Girls show has a mother and daughter story at its heart, with a television talent show as a backdrop.Emma and Mel C cried when they watched footage of the workshops; both felt it reflected the group’s ethos — friendship, identity and being true to yourself — and also saw it as an astute commentary on today’s obsession with celebrity.
