Radio broadcaster Karl Haas has died. His “Adventures in Good Music,” an hour-long program in which Haas blended music and talk aimed at casual listeners, was syndicated to hundreds of stations in the United States, Australia, Mexico and Panama and was broadcast by Armed Forces Radio. Haas delighted listeners with his vast musical knowledge and his penchant for punny program titles, such as “The Joy of Sax” and “Baroque and in Debt.”
