My, my, how could they resist you?

In “Little Shop of Horrors,” opening today at the Ahmanson Theatre, it truly is a horror when the show’s cute baby plant grows into the 6-foot-tall, 7-foot-long man-eating Audrey II.

But what if that great big plant opened its huge fanged mouth and starting belting out tunes by ABBA?

That horrific image is prompted by the fortunes of “Mamma Mia!,” the musical fashioned around the relentlessly sunny songs of the Swedish pop group ABBA. Since its first production in London five years ago, the cotton-candy show about a big fat wedding in Greece has grown faster than Audrey II and now seems bent on taking over the world.

The most recent factoid provided by the producers of the show, now in its third year on Broadway: Dutch record buyers have just made the Dutch cast recording No. 1 in its first week of release -- “the first time a cast recording has ever debuted at the top of the Top 100s in the Netherlands sales charts” (the Dutch-language production is playing in Utrecht). The original cast recording has gone platinum in the U.S. and Australia, double platinum in Canada, double gold in Britain and gold in Germany and Sweden.

And before you race off to Tower Records in search of the Dutch recording, consider these other “Mamma Mia!” statistics, also cheerfully provided by the producers:

* There are 11 productions of the show now running (eight resident productions and three tours) in North America, Australia and Asia.

* The show has been seen by more than 18 million people worldwide, and more than 18,000 people see it every night.

* “Mamma Mia!” has grossed $1 billion and counting at the box office.

* Three new productions are opening within the next 12 months.

It’s enough to make Audrey II consider eating the “Dancing Queen.”
