“The Phantom of the Opera” will extend its final Broadway run to April 16 due to soaring demand for tickets, producer Cameron Mackintosh said Tuesday.

The Andrew Lloyd Webber musical, which is Broadway’s longest-running show, was originally set to close on Feb. 18, as ticket sales were on the decline.

But sales spiked after news of the show’s closure broke in September, Mackintosh said in a press release Tuesday afternoon.

The production took in $2.2 million last week, marking the highest-grossing week in its nearly 35-year run, show sources told NY1. 

“The response to the news that ‘The Phantom of the Opera’ is finally going to end its record-breaking original Broadway run after 35 years has been as phenomenal as the show itself,” Mackintosh said in a statement. 

“We are all thrilled that not only the show’s wonderful fans have been snapping up the remaining tickets, but also that a new, younger audience is equally eager to see this legendary production before it disappears,” he added.

Tickets for the production’s extended run, as well as its Feb. 6 through Feb. 18 shows, will go on sale at 10 a.m. on Wednesday, Nov. 30, the release said. 

Only tickets for the show’s final performance on April 16 and a charity performance set to take place on April 14 will not be on sale at that time, according to the release. 

The April 16 show will mark the production’s 13,981st performance, the release noted. The musical debuted at The Majestic Theatre on Jan. 26, 1988.
