For the 75th anniversary of The Wizard of Oz, we celebrate the life and legacy of the freethinking lyricist Yip Harburg, who wrote “Over the Rainbow,” and many other songs. Listen to Yip himself singing “If I Only Had a Brain,” “Over the Rainbow,” “Brother, Can You Spare a Dime?” and “Last Night When We Were Young.” Then we interview Yip’s son, Ernie Harburg, also an atheist, a scientist who is director of the Yip Harburg Foundation, about his father’s artistic life and social activism.
