LOOSE ENDS: David Crosby, who’s been the subject of harrowing stories about drug addiction in recent issues of Rolling Stone and Spin magazines, has a new helper in his fight to keep himself out of jail over a string of drug and firearms convictions. He just hired attorney Alan Dershowitz, the lawyer who successfully defended Claus von Bulow in his recent murder trial. Crosby, who’ll be at the Golden Bear on Saturday, is also in the process of negotiating a deal to write his autobiography--or, rather, to tell the story to a writer who’ll turn it into an “as told to” autobiography. . . . Sting, who has been accused of arrogance and naivete because of the political songs on his “Dream of the Blue Turtles” LP, won’t convert his detractors with the full-page ad in the latest Billboard that shows an infant against a stark white background; handwritten in small letters is the date of the Reagan/Gorbachev summit, “November 19-20 1985,” followed by the line “I hope the Russians love their children too.--Sting.” The ad wasn’t intended solely to help the cause of diplomacy. “Russians”--a track from “Blue Turtles”--will be Sting’s next single.
