STAGE

“Starlight Express,” the $8-million roller skating musical about a railroad race across the United States, has again postponed its Broadway opening and will premiere on March 15, instead of Thursday night. “The actors simply need more performance time,” Bill Evans, a spokesman for the show, said Tuesday. The musical, written by Andrew Lloyd Webber and Richard Stilgoe and directed by Trevor Nunn, has sold $5 million worth of tickets. It was to have originally opened Feb. 26 at the Gershwin Theater.
