Spoiler alert: Things generally haven’t gone well for women who married King Henry VIII.

Until now.

“Six,” a slyly saucy pop musical about the ill-starred queens, has already stormed stages in Britain, North America, Australia and even on cruise ships. Embraced by a youthful fan base for its catchy (and social-media-amplified) score, it has been fast-tracked to Broadway, where it is previewing to full houses at the 1,027-seat Brooks Atkinson Theater before opening March 12.

The show, just 80 minutes long, has a simple conceit — They’re Tudor queens! And they’re pop stars! — as it imagines a concert in which the women compete for audience approval with songs describing marital misfortune (in two cases, beheadings). Think wall-to-wall wordplay about sex and schism, belted by a diverse group of performers whose style, sound and steps are inspired by superstars including Ariana Grande and Nicki Minaj.

“Six” is the remarkably recent brainchild of two remarkably young theater-lovers: Toby Marlow, a 25-year-old who refers to Beyoncé and Lady Gaga as “my mums,” and Lucy Moss, a droll 26-year-old who wears Harry Potter spectacles and neon-detailed Buffalo platform sneakers.
