ANN-MARGRET AT 81

  Ann-Margret has always spoken in a voice that falls somewhere between a purr and a coo. But at her home on a recent rainy day in Los Angeles, she broke up her usual gauzy tones with deep and gutsy growls. “One, two, three o’clock rock!!!” she half-bellowed and half-yelled over a video chat, echoing the opening line from “Rock Around the Clock,” Bill Haley’s raucous 1954 smash.

A few minutes later, she snarled through the opening salvo of “Splish Splash,” the highly caffeinated 1958 hit by Bobby Darin, only to follow it with the outburst, “I love rock ’n’ roll!” Her tone was far more Joan Jett than Kim McAfee, the sprightly character she played in “Bye Bye Birdie,” the movie that simultaneously made her a household name and the hottest pinup of 1963.

Ann-Margret — pronounced as one name, not two — has always been rock ’n’ roll adjacent, though that’s rarely talked about today given her long and varied career as an actress and a singer of lounge classics. She co-starred with Elvis Presley in one of his most beloved films, “Viva Las Vegas,” provided a flirty foil to a character meant to affectionately send him up in “Birdie,” and had a personal relationship with him of varying description.

Yet, it’s only now, at the improbable age of 81, that Ann-Margret is getting the chance to assert herself as a full-on rock ’n’ roll goddess — if a winking one. She recently released “Born to Be Wild,” the first album in the star’s career of 60-plus years to focus squarely on rock standards, all of which she handpicked, including Steppenwolf’s biker anthem referenced in the title and “Rockin’ Around the Christmas Tree,” which Elvis famously gyrated through in his own version.

The “Born to Be Wild” album cover drives that home. It reproduces a 1967 poster created for her first Vegas show that finds her in a form-fitting jumpsuit while straddling a Triumph Tiger motorcycle. “I don’t think I can get into that jumpsuit today,” she said, and laughed. “But I can sure try!”
