TELEVISION

‘Lucy’ Uncut: All 179 episodes of “I Love Lucy” and all 13 of the one-hour “Lucy” specials will be aired in their original, uncut forms beginning on Valentine’s Day on Nickelodeon’s Nick at Nite. For the first time in three decades, the series will be shown in prime time: On Feb. 14, Nick at Nite kicks off the series with a weeklong tribute to the show that starred Lucille Ball, Desi Arnaz, Vivian Vance and William Frawley with three hours of programming each night. Then “I Love Lucy” will show at 9 p.m. Monday-Friday. Each episode will be 26 minutes, an average of 18% longer than has been regularly seen in syndication.

* Murphy’s Expecting Two: CBS Entertainment has picked up “Murphy Brown” for two more years, through the 1995-96 season, at 24 episodes each. The comedy, now in its sixth year, is the heart of the network’s Monday night lineup. This year the program has experienced a rebound, with renewed focus on the newsroom and topical items, less on Murphy’s baby. Ratings are just about where they were last year.

STAGE

Please, Sir: Cameron Mackintosh, one of the world’s most successful producers of stage musicals, is taking a hard line about his next show, a London revival of Lionel Bart’s “Oliver!” expected next November with Jonathan Pryce. He’s allowing no other productions, whatsoever. That’s turned out to be bad news for a group of students at St. Aloysius Junior School in London. After practicing since last October for their version of “Oliver!” they were ordered to stop by Mackintosh’s production company, which invoked a law forbidding London area schools from performing plays that can be seen in the West End theater district. Despite complaints from parents, a Mackintosh spokesman held firm: “If 60 or 70 schools did it, then the number of parents who might not come to our production could be quite large.”

MUSIC

About Face: Oscar-winning film composer John Williams, conductor for 13 years of the Boston Pops Orchestra, will stay around for the spring season as music adviser to help plan this year’s concerts and to find his replacement as music director. Meanwhile, the orchestra will perform with guest conductors. Boston Symphony Orchestra President George H. Kidder said that the Pops’ tradition with Arthur Fiedler and Williams for the last 15 years dictates that the organization must take its time in choosing from the “wonderful range of talent we’ve seen.”

* No Shows: All music events scheduled for the month of February at Cal State Northridge have been canceled due to damage caused by the Jan. 17 earthquake.

Organizers estimate more than $1 million will be raised. Additional participating artists are to be announced.

* Pop Longevity: Diana Ross, the Beatles and Frank Sinatra receive special tributes at Monday’s “American Music Awards” airing on ABC--even though spokesmen for the Dick Clark-produced special said they did not expect any of the honorees to be present. Ross is celebrating her 30th year in the music and film business, and Sinatra has been performing for more than 50 years. As for the Beatles, they first arrived on American shores 30 years ago this month.
