After Dan Savage saw the Broadway production of The Book of Mormon, he went on Keith Olbermann’s news show and gushed about the brilliance of Trey Parker and Matt Stone’s musical masterpiece for 10 minutes straight. Reports from the road say the touring production is just as mind-blowing as the original. The entire run of Book of Mormon at the Paramount is sold out, but there will be 20 $25 rush tickets available by lottery two hours before every performance. (Paramount Theater, 911 Pine St,, 7:30 pm, $25)
