Andrew Lloyd Webber's current London production of Jesus Christ Superstar, which resides at the Lyceum Theatre, is still scheduled to close this spring. But the closing notice appears to have boosted ticket sales dramatically. Theatre owner Apollo Leisure is scheduled to meet with the Really Useful Group this week to discuss the future of Superstar, which was revived in 1996. No decision has been made yet as to whether the musical will finish its run this spring but if the show does close, it is likely that it will go on a national tour. A spokesman for Leisure says that Superstar "might extend to March 20," but nothing is finalized. However, if the show does close Leisure will not have a problem filling the theatre. Shows that are currently in line for a theatre include The King and I, Gypsy, and The Three Musketeers.
