NEW YORK Broadway sales started to gain a little summer sizzle in Week 2 (June 2-8), with most productions seeing receipts rise — though not, in general, in great leaps and bounds.Biggest gain of the sesh was seen by “Legally Blonde” ($590,753), which bumped up more than $140,000 on the same week that “Legally Blonde the Musical: The Search for Elle Woods” preemed on MTV, suggesting there may indeed by a B.O. payoff to the reality TV competish to replace star Laura Bell Bundy. Many of the individual boosts of the week were in the $30,000-or-less range, although two Disney offerings, “The Little Mermaid” ($976,491) and “Mary Poppins” ($789,723), stepped up by more than $75,000 each, and estimates for “Young Frankenstein” ($868,000) climbed around $70,000. Heading in to the Tony ceremony Sunday, “In the Heights” ($659,937) was up more than $50,000. Gains were minimal for fellow tuner nominees “Cry-Baby” ($232,269) and “Passing Strange” (213,088), while an additional $25,000 for “Xanadu” ($187,244) still didn’t push the show over the $200,000 mark. None of those offerings outpaced two popular revivals, with both “South Pacific” ($763,341) and “Gypsy” ($705,200) finishing out of the top 10. Top play of the frame was “Cat on a Hot Tin Roof” ($694,741), followed by Tony-nommed shows “August: Osage County” ($400,733) and “Boeing-Boeing” ($379,190). Total cume for the street climbed around $645,000 to $18.2 million for 34 shows reporting, or $19.1 million including “Frankenstein” estimates. Most of the frame’s box office dips were minimal, although “Rent” ($330,942) sank a mammoth $220,000. Blame it on the fact that biz the prior week had been juiced by the original closing announcement that the long-running musical was skedded to shutter June 1. The end date for “Rent” has since been postponed until September, so expect sales to build momentum again as the final perf approaches. The 26 musicals grossed $15,208,449 ($16,076,449 estimated) for 83.4% of the Broadway total, with an attendance of 202,405 at 77.5% capacity and average paid admission of $75.14. The nine plays grossed $3,031,224 for 16.6% of the Broadway total, with an attendance of 46,861 at 70.1% capacity and average paid admission of $64.69. Average paid admission was $73.17 for all shows.
