Robert Hazard, 59, the Philadelphia-bred rock troubadour who wrote the pop anthem "Girls Just Want to Have Fun," died unexpectedly Tuesday night after surgery at Massachusetts General Hospital in Boston, his widow, Susan, confirmed today.
Mr. Hazard, who lived with his wife and two teenage sons in the Adirondacks and in Vero Beach, Fla., last month had canceled a planned fall tour without explanation.
