GOOD MORNING: Ah, this is showbiz: “Would you like to open for me at the La Jolla Comedy Store?” It was young comic Pauly Shore to his dad, veteran funnyman Sammy Shore, who has opened for Elvis Presley, Frank Sinatra, etc. Yup, the two will play Mitzi (Pauly’s mom, Sammy’s ex) Shore’s boite tonight, Friday and Saturday. At Pauly’s first outing as a standup (at 18) at the Alley Cat Bistro, “I was nervous as a cat,” said Shore, pere. “But he was terrific. However, a week later, after a second date he called and said, ‘Dad, I bombed.’ I told him, ‘Welcome to showbiz’!”… And up in Seattle, Steve Allen was joined on stage at the Jazz Alley by his grandson, Michael — 12 years old! He’s a budding pianist and Steverino says the kid stopped the show cold … Add third generation: Carole Lief, daughter of Lynne and Ronnie Lief — and granddaughter of Edie and Lew Wasserman — played a standup at Santa Monica’s Up Front Comedy … And Leonard Lyons’ son Warren L. does his act “Life in the Lyons Den” at the Gardenia Friday night … Meanwhile, over at the Canon where it all started for him, veteran Jackie Mason was doing schtick about the O.J. Simpson trial and defense attorney Bob Shapiro, who was in the audience. Mason got a turn in court Wednesday, covering for his BBC weekly radio show. Comics on hand for Mason’s bow included Jerry Seinfeld, Buddy Hackett and Louis Nye … Cybill Shepherd canceled Wednesday night’s bow at the Cinegrill — laryngitis. She was skedded through Saturday. On hand for her dress rehearsal (in sneakers) Tuesday were pals including Peter Bogdanovich, Alan Rosenberg with Marg Helgenberger, Alicia Witt, Tom Werner, Jay Daniel and Mr. Blackwell. Cybill’s tunes included “But Not for Me,”‘Walking the Dog” and the Memphis belle’s own tune, “Talk Memphis to Me”– about which she kidded … The preem audience at the DGA for “A Mother’s Prayer” was so moved by the vidpic about AIDS orphans that celebs made donations to the AIDS Orphan Adoption Project after the screening. The telefilm bows Aug. 2 on the USA Network and the National Council for Adoption (NCFA) has given its 800-333-NCFA number to run at the tag of the airing for mothers who need help and for those who want to help. This is showbiz, too.GOVERNMENT INVOLVEMENT IN SHOWBIZ ratings systems “would be a catastrophe,” Jack Valenti tells the World Affairs Council at Universal tonight. Valenti told me he has no problem with the V-chip idea for an individual program, but not when it allows hours to be blocked out. He warns of the movements afoot in Congress and with the FCC. “It should be done by the movie and TV industry and not by Congress,” Valenti says adamantly. He’s been busy in town talking with everyone from producers, guilds, hardware producers, nets and studios about the digital revolution, whereby thousands of accurate copies of shows can be illegally reproduced quickly. “We have to craft legislation to protect intellectual property in the new rapidly moving technology as never before,” he warned … Before winding their first-look development deal at Par, Bill Cosby and Stan Robertson delivered ‘em a script by Scott Smith, a true story about the Navy’s first black deep-sea diver, Carl Brashear, who lost a leg while retrieving a nuclear warhead.

Robertson sez the story “makes one feel great about this country and the values which cut across all ethnic, racial and economic lines”… Anne Archer co-stars with Alan Alda in Robert Halmi’s CBS TVersion of Neil Simon’s “Jake’s Women,” Glenn Jordan directing … Who better? Bob Stack will be the on-camera spokesman for “Family Locator” pagers. After filming the commercials, Stack starts the new “Unsolved Mysteries” season … When Ed McMahon drives up to give contestants their million $ prizes, he’ll probably be driving a Mercedes: Charles Stern set McMahon for the auto blurbs, to film on the 29th. EDGAR BRONFMAN JR. WAS GLAD-HANDING Ron Meyer to all the studio toppers at Herb Allen’s annual Sun Valley conclave. Tom Pollock was there, as were Mike Ovitz, Michael Eisner, Bob Daly, Terry Semel, Sumner Redstone, Ron Perelman, Bill Gates, Warren Buffett, etc. … I spoke to lyricist Tim Rice in London, congratting him on his five shows playing the L.A. area — he was readying for meets with Alan Menken and “King David” to preem in Jerusalem in ’96. Rice is working on an album with Cliff Richardson and hopefully a show “Heathcliff,” with music by John Ferrar. Rice wings here soon for the “Aida” animated Disney feature, with music by Elton John.
