ON THE SECOND night of his New York crusade, evangelist Billy Graham got a little help from two friends - Bill and Hillary Clinton. The ex-President and New York's junior senator joined the crowd of 80,000 at Flushing Meadows-Corona Park, Queens, and were greeted like soul mates. The audience screamed as Bill Clinton took Graham's hand and spoke about previous revivals. "Hillary and I are honored to be here tonight . . . 46-plus years after I attended my first Billy Graham crusade," Clinton said. "I took Hillary in 1971, and in 1979, when he came back to Arkansas, I was the governor. So I've been doing this a long time.

" He said Graham won his heart decades ago when he refused to speak to a segregated audience. "I was just a little boy, and I never forgot it and I've loved him ever since," Clinton said. "He's about the only person I know who I've never seen fail to live his faith.

" Graham returned the favor, lavishing the Democratic power duo with praise. "They're a great couple," he said. "I told an audience that I felt when he left the presidency he should be an evangelist because he has all the gifts and he'd leave his wife to run the country.

" Mayor Bloomberg and Sen. Charles Schumer (D-N.

Y.) also attended last night's rally, which had a more youthful feel than the first night. A concert by the Christian pop group Jars of Clay helped pack the park with teens, and the 86-year-old Graham tailored his sermon to the younger generation. He threw in references to Madonna, the Rolling Stones and the new "Star Wars" movie and mentioned the time U2 frontman Bono visited his home. The kids gave the white-haired Southern gentleman the rock-star treatment. "I came for Billy Graham - then found out the bands were here," said Reid Ouse, 16, from Minnesota. Earlier in the day, the sandbox set was treated to a performance by Gotham's newest superhero, a Spandex-clad, sword-wielding do-gooder named Bibleman. He mesmerized an estimated 10,000 tots by spouting Scripture and kicking butt. Graham ends his crusade, which he says will be his last in the U.

S., with a rally this afternoon.
