Robert Hazard, the Philadelphia-raised musician and songwriter of hits such as Cyndi Lauper's "Girls Just Wanna Have Fun," died yesterday, of complications from pancreatic cancer. Hazard's longtime friend and former manager Bill Eib confirmed the news for the Daily News's Chuck Darrow earlier today. Hazard would have been 60 on Aug. 21. Hazard had surgery in Boston last week related to his cancer. He had recently postponed tour dates due to his health.
