At Thursday’s curtain call for “Jesus Christ Superstar,” Andrew Lloyd Webber and Tim Rice joined director Des McAnuff. For some reason, the composer felt compelled to remind the opening-night crowd at the Neil Simon Theater that they were not in a cineplex.“Everything you’ve heard is live and the band is live,” said Lloyd Webber. Rice pointed to the show’s original Judas Iscariot out front. “And it’s wonderful to see the wonderful Ben Vereen in the audience,” he said. McAnuff kept it even simpler. “Let’s party!” he ordered. Over at the New York Hilton, McAnuff mused on having his “Jersey Boys” playing just across West 52 Street from the “JCS” revival. “I still can’t get a table at Gallagher’s. But it is nice to go across the street and give notes to the ‘Jersey Boys’ cast,” said the helmer, who sees no competish from the upcoming “Evita” revival. “They’re great companion pieces. What a great season for Tim Rice and Andrew Lloyd Webber fans!” FYI, the tuner has the best pre-curtain warning, which goes: “If you have a lozenge or candy, open it whenever you like. The score will drown you out!” And it does.
