We remember one of America's great lyricists, Yip Harburg. He wrote over 500 songs including, "Somewhere Over the Rainbow," "Brother Can You Spare a Dime," and "It's Only a Paper Moon." We talk with his son, ERNIE HARBURG andhis wife DEENA ROSENBERG. They have collaborated on the newshow "Somewhere Over the Rainbow: Yip Harburg's America," which is showing this week in Philadelphia. Rosenberg worked closely with Yip Harburg for nearly a decade including working with him on the early concept of this show. Yip Harburg died in 1981.
