Andrew Lloyd Webber is puzzling TikTok with a “Phantom of the Opera”-inspired tribute to raunchy rap song “WAP” by Cardi B and Megan Thee Stallion.

The musical reimagining, cleverly titled “Phantom of the WAPera” after the Broadway legend’s 1986 musical (and, well, “WAP”), has amassed 1.9 million views.

In the bizarre video posted Friday, the 72-year-old UK composer can be seen grooving along to the dirty ditty, whose acronym stands for “wet ass p - - - y” and espouses the virtues of well-irrigated female nether regions. The brief clip concludes with Webber playing the famous “Phantom of the Opera” theme on the piano while “WAP’s” risqué lyrics sound in the background.

Needless to say, Webber’s “WAPera” blindsided users on the viral video streaming platform TikTok.

“This was a fever dream,” said one confused commenter about the remix.

“You have a TikTok,” wondered another in all caps about the septuagenarian.

However, others loved the “Cats” composer’s rendition. “This is everything I’ve ever wanted and more,” wrote one newfound fan.

“You are the actual king of TikTok!! Everyone needs you,” fawned another.

“Thank you,” replied Webber, who made headlines last month after lambasting the much-maligned movie version of his musical “Cats.”

Another gushed, “This isn’t real. I’m amazed. This is beautiful.”

Let’s just be glad that the elderly impresario didn’t attempt TikTok’s viral “WAP” dance, which has resulted in injury and hospitalizations for many internet clout-seekers.
