The new staging of Rodgers and Hammerstein’s “Cinderella” had a fairy-tale first week on Broadway, pulling in strong crowds and robust sales ($458,652 for just three previews) in Week 35 (Jan. 21-27), a frame that otherwise saw most shows decline vs. the prior sesh.Elsewhere, “Annie,” one of the newer musicals on the boards, and like “Cinderella” a family-friendly title, dodged the January slowdown that comes with the month’s typically reduced ticket prices. The tuner’s average ducat slipped $7 to $87.80, but attendance climbed notably, boosting sales almost $125,000 to $1,026,892. “Manilow on Broadway,” after a stellar first few previews, took an unplanned hiatus when the star performer fell ill. Week-to-week B.O. comparisons were affected by the prior sesh including the three-day Martin Luther King Jr. Day weekend. Overall Broadway sales fell $1.9 million to $17.2 million for the 23 shows on the boards, while attendance slipped to 182,952. The 18 musicals grossed $14,824,797 for 86.3% of the Broadway total, with attendance of 153,908 and an average paid admission of $96.32. The five plays grossed $2,358,048 for 13.7% of the Broadway total, with attendance of 29,044 and an average paid admission of $81.19.
