GOOD MORNING: One video missing from the VSDA doings in Vegas is O.J. Simpson’s “Minimum Maintenance Fitness for Men” from Playboy. Hugh Hefner says there is no way they would take advantage of the feeding frenzy on anything related to O.J. Hef told me they’ve been offered $ 15,000-$ 20,000 from shows like “Hard Copy” for excerpts of the tape — some of which lend themselves to double entendre, as you might imagine, about body parts, blood flow, etc. No way , says Hefner of the tape, which was in post-production at the time of the murders. Nor is there any plan for its release “unless something very unusual happens.” The video was made at a cost of about $ 250,000. However, Playboy’s October issue will feature a pictorial layout on Paula Barbieri, O.J.’s most recent date. Hefner reminds that Playboy’s had a plethora of players in the news of late: Patti Davis in July, N.Y. policewoman Carol Shaga in August and, in September, Robin Givens in pictures and text on Mike Tyson, and the about-to-be next Mrs. John Wayne Bobbitt. Also in September, David Geffen talks about “Making It in Hollywood” and homosexuality. Hefner, however, sez he’d nixed sexually explicit pix of then-Miss America Vanessa Williams. “They were offered to us but we decided to a man we were not going to dirty her career. I’ve never regretted it.” He adds Penthouse printed ‘em. He is particularly proud of “40 Years: The Playboy Book” (hardcover, General Publishing Group Inc.) by Gretchen Edgren. In it, he asserts Playboy “literally transformed the social-sexual climate of the country — and (became) the most influential men’s magazine in the world.” To prove his ardor for the book, Hef sez, “I’m going to do something I’ve never done before”: he’ll autograph copies at Brentano’s in Century City, Aug. 4.IT’S “LUST FOR MURDER” as the first play Doug Cramer will (hopefully) take to Broadway. Cramer teams with Bobby Fryer to produce his story of a N.Y. socialite who hires her hairdresser to kill her husband. Playwright Cramer decided to go ahead with this play instead of his “The Last Great Dish,” the camouflaged story of his deceased ex-wife, columnist Joyce Haber, which he previewed March 16 at the Tiffany. I reported at that time the reaction was strong — and divided. Some urged him to pursue it and others hoped he’d bury it. Some of those who were at that memorable evening reading also took in the fresh night air at Cramer’s “Biennial Barn Dance” this weekend at his La Quinta Norte ranch in Los Olivos. More than 300 of the usually black-tied showbiz-social-art community donned boots and blue jeans to be hay-wagon’d from Cramer’s palatial home through his vineyards, past his pond, zoo (llama, zebras, etc.) to his museum building, housing a modern/contemporary art collection that would make any city’s museum envious. And then the barn dance, barbecue and fancy banter well into the full moon’d night, meticulously arranged by host extraordinaire Cramer. Guests came by planes and limos from everywhere. Plus Cramer’s neighbors: He’s bordered on one side of his vineyards by Ray Stark’s ranch, with his impressive art collection on his grounds surrounded by corrals where he houses 75 horses. And on the other side of Cramer is Fess Parker and family and their vineyards, rated among the top in California. And nearby, the John Forsythes, who are new ranchers. Another neighbor there was Bo Derek. But neighbor Michael Jackson was not spotted doing the moonwalk with the step barn dancers … Among the art crowd, Roy Lichtenstein and Ellswsorth Kelly (well repped in Cramer’s museum), plus collectors like Steve Martin, Dan Melnick and the Gersh family. Beatrice (Mrs. Phil) Gersh receives MOCA’s first Distinguished Women in the Arts award Sept. 28 at the BevWilshire … The busy weekend wound with Yvonne Fedderson and Joanna Carson’s Marina cruise party aboard the RegentSea. The evening was a toast to the ChildHelp Charity, which the ladies generously support. TAKE TWO FOR BARBRA STREISAND, as nine cameras taped her Pond performances Friday and Sunday. Dwight Hemion, who with Gary Smith had taped her MGM Grand New Year’s Eve show, brought the cameras into the Pond as she updated her show for the HBO airing Aug. 21. It was thought, for a while, she’d do the show “live” from San Jose, but a last-minute change shifted to tape. Among the celebs there, captured on this tape, were former beau Don Johnson, Shirley MacLaine and her brother, Warren Beatty, and his wife, Annette Bening … Emma Thompson’s being talked for Robert Redford’s leading lady in “The President Elopes” at Castle Rock … Producer David Friendly and wife Priscilla Nedd-Friendly welcomed daughter Madeleine at Cedars-Sinai Saturday.
