If there are any Night People reading these lines this morning, please keep a peeper peeled for disc jockey Jean Shepherd. If you see him, tell him to go home, all is forgiven. Tell him to shave first, though, huh? He's gotta meet a sponsor. Of course it's not likely there are any Night People reading these lines. If you're a true Night Person, this time of the morning you're stashed away sawing seventy in your cool, dark pad where you can't catch sunburn germs. It won't do any good for you Day People to look for Jean. Even if you saw him, you'd just think he was a bum. He's wearing his anti-meatball camouflage. Readers of this space may remember Jean. He's the New York after-midnight disc jockey and true patriot who's been trying to save America from the horrors of "creeping Meatballism." He's disappeared after radio station WOR fired him for giving a free commercial to a soap company. The company was so pleased with Jean's kind deed now wants to sponsor him on a four-hour program every Sunday night. Naturally, they are willing to give WOR a small fortune and all the soap coupons it can use for the privilege. So WOR wants Jean back. Now who's a meatball? The station backed up its plea by having the all-night DJ who replaced Jean broadcast appeals for him to "come home, all forgiven." Big ads were placed in newspapers. "Jean Shepherd," one ad said, "if you see this ad please contact us at once. Major soap manufacturer wants to sponsor you over WOR commencing Sunday night at 9:05 p.m. Urgent!!! WOR Radio." "We've got to find him by tomorrow," Dick Jackson, head of the station's public relations department, said Tuesday. That's our deadline for scheduling next Sunday's shows. We've already bumped several programs, religious programs and if Shepherd doesn't turn up, we'll just have to play music." Jean began creating a stir several weeks ago with a literary hoax at the expense of the Day People. His Night People listeners swamped libraries and book stores with requests for a non-existent book titled "I, Libertine." Meantime, Jean's employers slipped him the ol' pink slip with his paycheck. Advertisers were complaining, they said, that his salt-of-the-earth Night People between them couldn't raise the down payment on a postage stamp. Well, on his last program Jean got to feeling mellow toward soap companies, and, wotinall, he had nothing to lose. So he gave a free plug for a well known soap company whose name I dast not mention because they might not have bought an ad in this sheet today. Jean was cut off the air immediately. That's when he disappeared into the night.
