E.Y. Harburg affectionately known as "Yip" was one of the greatest American songwriting lyricists. He wrote countless famous songs, lyrics for Wizard of Oz including Somewhere Over the Rainbow. One of his most famous song with tune by Jay Gorney was Brother Can You Spare A Dime which keeps getting revived for good reason. With Burton Lane he wrote the lyrics for Finian's Rainbow with such gems as How Are Things in Glockamorra and Old Devil Moon.
