Mike Tyson wasn’t quite a Broadway knockout last week, but the New York bow of the boxer’s solo show nonetheless posted healthy numbers. That was one of the factors keeping the Main Stem’s overall cume on solid ground — despite sales slippage at almost every other individual production on the boards.

“Mike Tyson: Undisputed Truth” pulled in $624,496 from six perfs, a relatively strong showing for a small-scale non-musical, with crowds drawn by the high profiles of the boxer as well as Spike Lee, who directed. Autobiographical outing, which initially bowed in Vegas, will play five more perfs at the Longacre.

Also adding coin to the pot last week was a spike at “Fela!” ($568,727), rising a whopping 63% in the final week of its limited summertime run. That show wasn’t the only one to benefit from last-minute sales: Jim Parsons starrer “Harvey” ($707,136) pulled in some additional cash by playing an extra, ninth perf in its final frame on the boards, while “Memphis” ($657,688) also picked up in what was the last sesh of its own run.

Other upticks were generally slight, with “The Book of Mormon” ($1,633,673) stepping up only a bit but easily crossing the $100 million mark in overall sales. A few plays — including “Peter and the Starcatcher” ($493,926), “Clybourne Park” ($393,487) and “End of the Rainbow” ($237,516) — also inched higher, compared with the previous sesh.

They were all among the shows that kept Broadway’s total sales at $23.5 million for 28 shows on the boards. That’s just slightly ahead of the prior week’s tally.

Bringing that number down, however, were a few significant slowdowns. “Evita” ($1,020,443) fell by more than $225,000, a drop attributable to the one-show absence of topliner Ricky Martin. “Bring It On” ($387,388) also fell thanks a shortened week of only seven perfs that accommodated press previews and the comp-heavy opening night, and in an indicator that producers made the right decision to close, “Ghost” ($502,195) slid by 14%.

Rialto cume will likely take a hit this week, with the exits of “Harvey,” “Memphis” and “Fela!” poised to tamp down the numbers along with the absence of Martin, skedded to be out of “Evita” for this entire frame.
