Starlight Express is an evening of mindless camp fun. And therein lies the problem. The opening of the first London revival of Andrew Lloyd Webber and Richard Stilgoe’s musical comes forty years after the show’s premiere at the Apollo Victoria Theatre, and must be a bittersweet occasion for the show’s composer. It was, after all, his son Nick, who, at the age of five, inspired him to write the show in the first place. Sadly, Nick wouldn’t live to see this first revival, having passed away from cancer in March of last year.
