Anchorage Mayor Tom Fink, who Thursday barred the rap group 2 Live Crew from using the city's civic center for a scheduled August performance, yesterday explained his reasons for giving the group Alaska's cold shoulder.

Fink, who says he has never seen or heard the 2 Live Crew perform and has no intention of doing so, denied at a news conference that he was exercising censorship by barring the group.

"I'm more concerned about the Egan Center. I don't know that much about obscenity," Fink said.

What he does know is that a near-riot ensued after the 2 Live Crew failed to perform at a scheduled event in Dallas last week, he said. The incident has made the group particularly unattractive to insurers, he added.

"In my opinion, if we can legally stop them from using city buildings, we should," Fink said. "I don't need that kind of problem -- riots, broken-up buildings and furniture."

Trial for Kelsey Grammer

"Cheers" star Kelsey Grammer has been ordered to stand trial on a cocaine possession charge after failing to enter a drug treatment program. Grammer, 35, plays the egocentric, patrician Dr. Frasier Crane in the hit NBC comedy series.

Grammer made no comment Thursday as a Van Nuys, Calif., Superior Court judge rejected a defense request to give the actor another chance to complete the drug program. The cocaine charge, which carries a maximum sentence of three years, could have been dropped after the program.

Grammer is accused of possessing about a quarter-gram of cocaine, which police said they found in the back seat of a patrol car after bringing the actor in on a warrant for an outstanding speeding ticket. The Nixon Library's Guest List

Four Watergate figures and former advisers to Richard Nixon -- John Dean, G. Gordon Liddy, Jeb Stuart Magruder and Donald Segretti -- reportedly aren't invited to the dedication of Nixon's presidential library.

However, H.R. Haldeman, Nixon's former chief of staff, is among the 3,000 people invited to the ceremony next Thursday at the $21 million Richard Nixon Library and Birthplace in Yorba Linda, Calif., 30 miles southeast of Los Angeles, according to a report in the Orange County Register.

"There was no discrimination in choosing guests," a library spokesman said recently. "Those invited were recognized for their help in building the library ... some personal friends of the president and local people."

Liddy said he was puzzled by the snub. "Beats me. I have the utmost respect for President Nixon," he said.

"I don't know why I didn't get an invitation," Magruder said. "I'm not a political animal, so I probably wasn't on any of their invitation lists." 'Crimes' in South Africa

Director Woody Allen has authorized the showing of his movie "Crimes and Misdemeanors" at a Johannesburg film festival next month despite a worldwide cultural boycott of South Africa because of apartheid. The festival is sponsored by the African National Congress and other anti-apartheid groups. Allen said he approved the screening to promote "a unitary culture and show sympathy for those in South Africa who oppose an ... unacceptable racial policy." They're Adults, Charlie Brown

Forty years after starting his "Peanuts" comic strip, Charles Schulz said he plans to introduce an adult for the first time into the fantasy world populated by Snoopy the dog and various children, but only on a television special.

Schulz, 67, spoke to reporters for more than an hour at an exhibit of his work at the San Francisco Cartoon Art Museum.

The cartoonist said the TV special is on the drawing boards for next year. The adult will have only a small part and will be a character who works at a puppy farm where Snoopy and his brothers, Spike and Olaf, meet for a reunion.

Schulz said he has never used adults in his newspaper comic strips because the strips are too narrow. "They would bang their heads on the top of the panel." Uncle Miltie at 82

Comedian Milton Berle celebrated his 82nd birthday Thursday in Los Angeles with a bash that brought together old friends and stars who may have watched television's "Uncle Miltie" when they were just kids.

"All I can say is at 82, if I had it to live over again, I'd live it the same sweet -- or not-so-sweet -- way," Berle said. "At 82, I feel like a 20-year-old, but unfortunately there's never one around."
