NEW YORK (ES) -  Bono turned down an honorary degree. The U2 frontman's 21-year-old daughter Eve Hewson will graduate from New York University (NYU) next week and while the institution hoped to have her famous dad involved in the graduation ceremony he ''politely declined'' the offer, according to the New York Post newspaper. NYU offered the singer and humanitarian an honorary degree as a Doctor of Humane Letters and invited him to give the commencement speech at the affair at Yankee Stadium in New York City, but Bono, 53, turned down the honour because he doesn't want to detract from his daughter's big day.
