NEW YORK — The spring frenzy begins.Five new Broadway shows started previews during Week 43 (March 20-26), helping the Rialto outdraw even the previous week’s strong showing. The 30 shows on the boards took in $17,146,090, up about $800,000 from the prior sesh. Among the new offerings are two big-budget tuners, “Tarzan” and “Lestat,” that everyone has their eye on. The $149,856 taken in by Disney’s “Tarzan” might seem like a pittance, especially by “The Lion King” standards. But the show played only two performances — part of an unusual sked of staggered previews that allows the show’s creators to tinker on dark days — and the top pre-opening ticket price is just $75, the lowest on the Great White Way. Attendance for “Tarzan” hit 100%. “Lestat” did some robust biz of its own during its one-performance week. Show brought in $113,807 from a house that was more than 96% full. Also looking good: The Roundabout’s “Threepenny Opera” ($361,936), playing five perfs to auds that were more than 95% of capacity. Rounding out the rookies were “Festen” ($201,085 for five perfs) and “Awake and Sing!” ($70,594 for three). Elsewhere on the Rialto, “Jersey Boys” ($997,640) broke another house record at the August Wilson. “The Producers” ($796,265) saw the biggest drop, after a booming sesh last week. And heading toward its March 30 opening, “Well” ($91,296) continues to post low numbers, hoping a dose of critical praise might help it get better. The 22 musicals grossed $14,716,391 for 85.8% of the Broadway total, with attendance of 195,912 at 94.0% capacity. The eight plays grossed $2,429,699 for 14.2% of the Broadway total, with attendance of 37,149 at 73.4% capacity. Average paid admission was $75.12 for musicals, $65.40 for plays and $73.57 for all shows.
