In the first of what could be several changes soon in its Saturday night lineup, Fox Broadcasting has announced that "Boys Will Be Boys" debuts at 8 p.m. Saturday, Jan. 16 ...

"Boys" is the revamped -- and retitled -- version of "Second Chance," which featured Kiel Martin as a young chap who is reincarnated and given the chance to make good in life ...

Not worth a third chance, the old show has remained in the 3.0 Nielsen range. Now Fox has dropped the concept and Martin. The rest of the cast (Matthew L. Perry, William Gallo, Demian Slade and Randee Heller) and their characters return as a bunch of fun-loving teen-agers coming of age in California. A Fox official explained Friday that "the teen demographics were very high, even at 9:30 p.m." ...

In the new lineup, "Boys" will kick off at 8 p.m. Saturdays, followed by "Women in Prison," "The New Adventures of Beans Baxter" and "Mr. President" ...

Fox is expected to introduce the hour-long "Dirty Dozen" in the Saturday lineup shortly after the first of the year but so far no hint of what two shows will be dropped on its arrival ...

Fox's Saturday and Sunday lineups, seen on 117 affiliates around the country (including WTTG here), trail Big Network shows every week in the ratings, although "21 Jump Street," in the 6-rating range, is always within whispering distance of the lowest-rated shows from ABC or CBS...

ABC Entertainment has announced a four-hour miniseries, "The Richest Man in the World: The Story of Aristotle Onassis," which goes into production next month in Spain ...

Raul Julia will play Onassis; Jane Seymour is cast as Maria Callas, Ari's longtime girlfriend; Anthony Quinn will play his dad Socrates; Francesca Annis will play Jacqueline Kennedy; and Lorenzo Quinn will play his son Alexander ...

Leftovers from recent Holiday Banquets: Those three ABC Christmas specials Wednesday ended up tying NBC's lineup that night from 8 to 11 with a 14.3 Nielsen rating overall and a 23 percent audience share. That's only a smidgen off the performance the week before of ABC's regular sitcom lineup and "Dynasty." CBS was close at 13.8/22 ...

On ABC, "A Muppet Family Christmas" did a 16.1/25; "Julie Andrews: The Sound of Christmas" slipped to a 14.6/23; while a reprise of the 20-year-old "A Christmas Memory," narrated by the late Truman Capote, did a 12.1/21 ...

On Thursday, ABC's "The Three Kings" drew an 8.2/13 between 9 and 11, no match for the NBC lineup, which averaged a 22.5/37, or even CBS' 13.5/22 for the same two hours (each rating point represents 886,000 TV homes) ...

Moving Right Along

A Los Angeles judge late Thursday dismissed actress Martha Raye's $10 million suit against comedian David Letterman, ruling the NBC star was clearly joking when he said in a TV monologue on March 5 that she was a "condom user" ...

Superior Court Judge Norman Epstein said, "No one could reasonably understand {Letterman's remark} in a defamatory sense. The remark was delivered as a joke, apparently intended as a parody" ...

The host of "Late Night With David Letterman" had said, "I saw the most terrifying commercial on television last night featuring Martha Raye, actress, condom user" ...

Raye sued for $10 million, claiming the remarks implied she was "sexually promiscuous and unchaste" and "personally uses condoms in some form of deviant, aberrant or socially unacceptable ... behavior" ...

Letterman's attorney said he was trying to parody Raye's commercials for a denture adhesive. Raye's attorney earlier said his client may appeal the ruling "on the principle involved" ...

CBS News' "West 57th" is headed for another cast change soon ...

Bob Sirott, who handles the lighter side of things on the Saturday night magazine, apparently wants out of his contract, which expires in April 1989, and the network isn't objecting very hard ...

Jane Wallace, another of the original cast of the show (along with Meredith Vieira and John Ferrugia), leaves at the end of this month. She'll be replaced by Karen Burnes, formerly of ABC News. Steve Kroft, one of the better writers in TV these days, joined the on-air talent earlier this year. Sirott, who earns $225,000 a year, wants to return to broadcasting in Chicago. Still too early to talk about his replacement ...

By the way, CBS News Friday confirmed our report that two ABC News producers turned down recent offers to jump to the "48 Hours" staff but insisted that "about two dozen" ABC News re'sume's, including that of a senior producer, are still in the CBS computer. So there ...

Regarding "48 Hours," which debuts in the 8 p.m. Tuesday timeslot on Jan. 19, CBS News president Howard Stringer held a pep rally for most of the new show's staff of 46 on Friday ...

The concept -- blanket coverage of a subject over two full days, a` la "48 Hours on Crack Street" -- is regarded as Stringer's baby and Friday he characterized it as a blending of CBS "tradition" with an innovative form ...

Andrew Heyward, executive producer of "48 Hours," said later Friday that hiring is complete except for a broadcast associate. The 46 total includes anchor Dan Rather, a dozen producers and six associate producers, most of whom have worked for CBS News before. Not counted are the free-lance camera crews that will work at the remote sites ...

Still no decision on the subject of the premiere show. They've just about completed work on "Miami Fights Back," taped recently in Florida. Another candidate for the debut could be very busy Stapleton Field in Denver, which "48 Hours" hopes to visit over the end of the New Year's weekend ...

Heyward is high on the prospects for the show, which he hopes will be "unpredictably vibrant and interesting. We're not presuming to do the 'documentary of the week' and we're not trying to vie for the 'good citizenship award' every time out. It's a different kind of journalism -- instead of packaging a subject within a severe time restraint we'll have the luxury of watching natural sequences of an important national story unfold over two days" ...

Now This

Starting Sunday, Jan. 3, NBC News' "Sunday Today" will move up to a 9 a.m. start on Channel 4 here. WRC is one of four NBC-owned stations where the move is taking place as a tactic to confront CBS' "Sunday Morning" dead-on in major markets that also include New York, Chicago and Cleveland ...

Since it debuted Sept. 20, Nielsen ratings for "Sunday Today" have averaged a minuscule 1.6/9, compared with a 4.1/17 for the excellent CBS entry, although the NBC show does build audiences over the 90 minutes. Affiliates will continue to get "Sunday Today" at 8 a.m. ...

The 50-member WETA board of trustees has 12 new members, including five elected by the WETA membership ...

CBS will introduce a revised Saturday morning kiddies' lineup on Jan. 2, adding 13 new episodes of the syndicated "Dennis the Menace," based on the Hank Ketcham comic strip, and returning "Galaxy High" reruns ...

Locally, Channel 9 viewers will find "Dennis the Menace" replacing "Teen Wolf" at 11:30 a.m., but local programming replaces the rest of the CBS kiddies' lineup that morning, so "Teen Wolf," rescheduled for noon, and "Galaxy High," at 12:30 p.m., probably won't be seen. The now-unseen "Kidd Video" and "CBS Storybreak" will bid adieu as of Dec. 26 ...

In the most recent national Nielsens, the NBC Saturday a.m. lineup led with a 4.5 rating and an 18 share (its 13th weekly win in a row), followed by CBS at 3.8/15 and ABC at 3.7/15. Considered an endangered species for several years, the Saturday morning lineups on the three networks have dropped another 40 percent overall in the ratings since Nielsen's peoplemeters went into effect last September ...
