Written in 1930 by lyricist E. Y. "Yip" Harburg and composer Jay Gorney, "Brother, Can You Spare a Dime?" was part of the 1932 musical revue "Americana"; the melody is based on a Russian-Jewish lullaby Gorney\'s mother had sung to him as a child. It was considered by many to be anti-capitalist propaganda, and almost dropped from the show; attempts were made to ban it from the radio. The song became best known, however, through recordings by Bing Crosby and Rudy Vallée both of whom were themselves Republicans that were released right before Franklin Delano Roosevelt\'s election to the presidency on November 8. The Brunswick Crosby recording made on October 25 with Lennie Hayton and his Orchestra became the best-selling record of its period, and came to be viewed as an anthem to the shattered dreams of the era.', '"Brother, Can You Spare a Dime?", also sung as "Buddy, Can You Spare a Dime?", is one of the best-known American songs of the Great Depression.
