Holy kabbalah! The Material Girl has returned.

Madonna (search) version 47.2 is a tricked-out '70s disco queen with platinum feathered hair, channeling John Travolta in "Saturday Night Fever."

She's ditched the political commentary (at least musically) and her first single, "Hung Up," is sampled from a 1979 ABBA hit, "Gimme Gimme Gimme."

She's returning to why we loved her in the first place -- handing fans a gift album, "Confessions on a Dance Floor," (search) to be released Nov. 15, made entirely of '80s-style dance tracks.

This Friday, MTV will air her new documentary, "I'm Going to Tell You a Secret," filmed behind the scenes of last year's much-praised Reinvention tour.

Yes, there have been career low points where even hard-core fans have rolled their eyes -- the Michigan native's sudden British accent? The alter-ego Esther? And let us never forget "Swept Away."

Her lowest-selling album, "American Life," considered a disaster by critics, still sold 4 million copies in 2003.

But in a career spanning two decades, she's bound to have a few bombs. And if her appearance on "Total Request Live" (search) Monday is any indication, she's got her mojo back. Madonna says it will make people "jump out of their seats."

At 47, she still has attitude, and she can still draw bigger crowds that any teeny-bop band around.

Considering the still-broken rib and protruding collarbone caused by a recent horse-riding accident at her English estate, she was a good sport, staying for the entirety of "TRL."

Dressed in a royal blue dress and matching eye shadow, she looked like a mom from the set of "That '70s Show," but somehow it worked.

She certainly had the hairstyle, even referring to her 'do as a "weenie roll." On her album cover, the "o" in her name has been turned into a disco ball.

Her recent comments -- she doesn't let her kids watch television, "the beast is the modern world we live in" -- is vintage Madonna. It was the same with "Like a Virgin" and "Like a Prayer" -- she's stirring things up to get a rise. Does the woman who made her living as a video queen really prevent her children from turning on the TV? Don't believe it.

They probably sat down to watch the video for "Hung Up," in which Madonna looks like she's on a mission to get past the doorman at Studio 54. The Farrah hair is resurrected, the background is packed with dancers, and Madonna struts down a city street at night, wearing skinny jeans, a sequined belt and a black leather jacket. Hot.

Damon Gonzalez, 29, creator of MadonnaFactory, a Madonna fan club, caught a glimpse and said he loves the latest incarnation.

"Madonna's a pioneer," he says. "Most pop stars today are anorexic, drugged out or are dangling their kids out of windows. She knows how to take a fall and get back up."

She can go on with her prim and proper English countryside routine of late, that's fine. But really, it's not truly Madonna if she's not pushing someone's buttons -- and she still manages that.

One song on "Confessions" called "Isaac," dedicated to a 16th century Kabbalist rabbi, has other rabbis in a rage.
