Crooner helps rise tuner B.O.

Usher ushered in a nearly $250,000 boost for “Chicago,” the 10-year-old revival in which the pop/R&B star began performing last week.

The tuner pulled in $747,330 for the week ending Aug. 27, a rise of about $243,000 from the previous week, putting it in the top 10 for the first time in a while.

That extra quarter-million dollars helped keep total Broadway sales for the sesh steady, ringing in at $15,411,361.

“Tarzan” ($696,926) swung downward by more $90,000 — which seems a big dip to take before the anticipated Labor Day slowdown. But folks at Disney say they saw the drop coming, and that, based on the advance, box office doesn’t look likely to fall much further, even after next weekend. New “Tarzan” ads for TV and radio roll out soon.

“The Producers” ($518,278) also brought in surprisingly low numbers last week, fueling questions that maybe the show won’t have the longevity first suggested by its megahit Rialto debut five years ago.

“Sweeney Todd” ($427,014) seems to be getting some last-minute biz, up by more than $60,000 in its second-to-last week on the boards. Also skedded to close Sept. 3 are “Dirty Rotten Scoundrels” ($464,347) and “The Lieutenant of Inishmore” ($151,359).

Of Broadway’s recent openings, “Martin Short: Fame Becomes Me” ($401,053) continues a slow rise, and “Kiki & Herb: Alive on Broadway” ($136,062) made a bit more money in the second full week of its monthlong run.

“Jersey Boys” ($1,118,583) broke its 15th box office record at the August Wilson. That show joined “Wicked” ($1,424,998) and “The History Boys” ($707,203) as the SRO shows of the week, all three playing to 100% capacity or more.
