City Paper editor Mark Perry had a big day Wednesday. He learned he is about to be elected unopposed as the new president of the Washington Independent Writers, and he was served notice that he lost his job. Perry, the fourth editor of the City Paper in four years, had held the job for two years. He once was editor of the Truckers News of the National Association of Truck Stop Operators, but on principle left that position when former Nixon press secretary Ron Ziegler became president of the organization . . .

This is going to be another great weekend for star watching in town. The stars of the new movie "Perfect," Jamie Lee Curtis, John Travolta and Marilu Henner, are here for a special showing of the film tonight at the Uptown Theatre with a party afterward at the Chevy Chase Athletic Club. Since the movie, written by Washingtonian Aaron Latham ("Urban Cowboy"), has something to do with sweating fashionably under a hot Nautilus for a perfect body, it's somehow fitting to party among the machines . . . And over at the Watergate Hotel, Robert Guillaume, Linda Evans, John Forsythe and Julia Migenes Johnson are getting ready for their appearance at Sunday's Ford's Theatre Gala. One group of stars, the Berosini Orangutans, will be elsewhere in their elaborate motor coach . . .

After his birthday party at the vice president's mansion, Bob Hope, his wife Dolores and a group of friends showed up at the Jockey Club for dinner Wednesday and then moved to the Fairfax Bar where pianist Steve Ross performs nightly. USIA director Charles Wick, who likes to show off on the keyboard whenever he gets a chance, asked if he could play the piano while Dolores Hope sang. Ross said they could wait until he finished the set. The party listened for a while and then left without Wick and Hope performing . . .
