There's going to be an Oliver North Day Aug. 15 in the Marine's home town of Philmont, N.Y., but a proposed ecumenical worship service has been called off because a local Roman Catholic priest wouldn't participate. The Rev. Charles Gaffigan says he thinks a celebration for the former National Security Council aide is an inappropriate occasion for such a service.

Philip Mossman, mayor of the town of 1,642 where North grew up and served as a Catholic altar boy, said he is disappointed about the canceled service but expects a "big turnout" for the rest of the day's events. But, "Larry {North is known as Larry there} is the biggest thing to come out of this town," the mayor said. It's not yet clear if North will show up for the celebration, which has been combined with the town's annual Community Day and features a fishing derby, a lobster steam, square dancing and the music of a one-man band. "He's been invited," Mossman said. We know he's received it, and the longer we wait for his answer the more we expect he might be coming."

Some folks who apparently will be there, the mayor said, are members of a group called PREVENT, who are scheduled to mount a peaceful protest of Oliver North Day because they feel he has "debased" the Constitution.

Out and About Yesterday, at the end of the long Iran-contra hearings, National Public Radio sent a photographer to the hearing room to take pictures of its news staff who had covered the historic event. Since the room was quickly emptying, NPR senior news analyst Daniel Schorr decided to pose at the witness table. Just then, Sen. Daniel Inouye walked in, said, "Dan, you can't testify without your counsel," and in an exaggerated imitation of North's attorney, Brendan Sullivan, put his arm around Schorr and whispered meaningfully into his ear for the camera. When Schorr asked Inouye how he should testify, the Senate committee chairman advised: "Tell them BS, Dan" ...

It seems that actor Sean Penn of spitting and punching fame has begun serving his 60-day jail term for hitting a film extra and for reckless driving, both violations of a probation sentence for an earlier temper tantrum. Careful to avoid serving his sentence in the Los Angeles County lockup, where some real tough guys might take umbrage at Penn's poor manners, the 26-year-old actor is paying about $60 a day to serve his term in a small jail in Bridgeport, Calif., near the Nevada border. He's in a private cell in a 12-cell area holding 10 others, jailed mostly on misdemeanors. He'll stay there until Thursday, when he will be released to keep a filming commitment in West Germany, and is scheduled to return Aug. 22 to serve the remainder of his term ...

Before it became the Ritz-Carlton Hotel, it was the Fairfax Hotel. Maybe that's why Lord and Lady Fairfax had lunch at the Jockey Club there yesterday. The couple, members of the ancient English family that gave Fairfax County its name and that once owned 5.2 million acres of Northern Virginia, weren't here for reparations: The family lost the land in the Revolutionary War and the British government compensated the Fairfaxes with about $20,000 ...
