Upcoming guests of Jimmy Fallon’s late-night show might want to negotiate their walk-on music with the show’s bookers, after the Roots played Fishbone’s “Lyin’ A--
when GOP presidential candidate Michele Bachmann walked onstage Monday night.

Musical editorializing is a Roots signature gag on the show, though Monday’s intro maybe “takes the cake,” as Roots drummer Questlove tweeted earlier Monday night. He also wrote, “late night walkon song devotees: you love it when we snark” and “ask around cause I ain’t tweeting title” — which maybe should have been a red flag for NBC late-night suits?

NBC was courageously declining to comment at press time. But anyway, we’d urge you to put your money on NBC suits’ keeping just a teensy bit closer eye on the Roots’ music choices — particularly when Fallon is hosting presidential candidates. Fallon has reportedly smiled indulgently while the Roots:

●Played a Milli Vanilli tune by way of introducing Ashlee Simpson — she of the lip-syncing “Saturday Night Live” hoedown debacle — on Fallon’s show. (Fallon’s program and “Saturday Night Live” are exec-produced by Lorne Michaels, who said he was blindsided by Ashlee’s “SNL” lip-sync.)

●Broke into E.U.’s “Da Butt” to welcome Serena Williams.

●Introduced Joan Rivers with Lady Gaga’s “Poker Face.”

●Performed Beck’s “Loser” to herald the entrance of “Speidi” on the show.

It’s unclear how NBC will handle the Bachmann entrance on The Walk On Project series, which was found on the Fallon show’s blog and which is dedicated to chronicling the Roots’ walk-on selections. It notes: “Questlove and co. always choose such thoughtful, awesome songs — take a look!”

At press time, you could still see Bachmann’s entrance on the home page of NBC, although some news media reported that it had been taken down at one point during the day.

Kardashian perfect

Professional baby-Kardashian Rob took the lead over professional weight victim Ricki Lake and professional actor/

motivational speaker J.R. Martinez on Monday’s “Dancing With the Stars.”

The scoring was an upset that produced the least-watched performance finale ever for a fall edition of the popular ABC competition show.

That said, the late blooming of the Kardashian brood’s famously un-famous sibling attracted an average of 19.6 million viewers.

In Monday’s performance finale, in which Rob Kardashian finally achieved a perfect score from the show’s three judges for his freestyle dance, judge Carrie Ann Inaba crowned him a guy-Cinderella who’d made it to the ball. Judge Len Goodman gushed, “You had more rise-and-fall than Pam Anderson jogging” — which passes for high praise on this show.

Show host Tom Bergeron called Rob “Cinderfella” — a reference to a Jerry Lewis feature film take on the Cinderella story that appeared to be way too highfalutin a reference for Rob, judging by his reaction of total bewilderment.

Fortunately, celebrities are not judged based on brains on this show, and Rob snagged a perfect score of 30 for his second dance, putting him ahead of the other two finalists, causing an eruption of screaming Kardashians in the audience.

So no cement ponds?

Earlier this millennium, CBS — once a proud member of the Viacom family — failed to mount a reality series called “The Real Beverly Hillbillies” amid widespread outrage.

Now, another Viacom property has taken up the cause, as the show gets an MTV once-over and is reintroduced under a new name: “Buck Wild.”

And by that, we mean that it will now be about a bunch of millennials who, MTV programming chief David Janollari told TV Guide, “live life to the fullest and have pride in their community and their circle of friends.” That includes “taking part in regional pastimes like mud racing, squirrel hunting and rope swinging.”

“These kids have the same kind of issues and goals and desires as we all do,” Janollari explained. “They all want to find true love or have families. They just live in a world that’s really different than many of us live in.”

That did not fool the West Virginia Film Office, which has denied the show producer’s application for state tax credit.


That, according to the Charleston Gazette.

The office director, Pam Haynes, said New Remote Productions got the brusheroo twice because it could not offer assurances that the show would not cast the state in a negative light. All applicants for the tax break must submit a general synopsis of their production’s theme so the film office can make sure an applicant “has at least good intentions in representing the state.”

Apparently, the MTV project did not pass the “good intentions” test.

The West Virginia Film Industry Investment Act affords tax credits to filmmakers and production companies — up to 31 percent credit — if they film in West Virginia, the Gazette reported.

“The legislation is clear,” Haynes told that publication, “that a production company can’t participate in the program if it shows West Virginia in a derogatory manner.”
