We expect there are sweaty palms, stomachs full of butterflies and a pervasive sense of impending doom over at Showtime Challenge HQ as the cast of Crazy For You start their first rehearsal tomorrow night. They'll have 48 hours to put a West End musical together ready for curtain up on Sunday. The game cast gave an al fresco concert outside the Actor's Church in Covent Garden last weekend raising a remarkable £400 in donations for Cecily's Fund, the beneficiary of this showbiz madness. You can do your bit by buying a ticket to see the show at the London Palladium on Sunday at 7.30pm. Book now and support this crazy Crazy For You.
