In London, “The Book of Mormon” earned the largest single-day gross in theater history. In New York, it inspired ticket counterfeiters. And in Boston, competition for seats to the irreverent, Tony Award-winning show — which opens a three-week run at the Boston Opera House April 9 — has made it the hottest ticket in town, and the most expensive since “The Lion King” revival back in 2004.
Would you pay $250 per ticket? Or $400? Or $1,000? It’s that hot.
