Allan Sherman was the Larry David, the Adam Sandler of 1963. He led Jewish humor and sensibilities out of ethnic enclaves and into the American mainstream with explosively funny parodies of classic songs that won Sherman extraordinary success and acclaim across the board, from Harpo Marx to President Kennedy. Here, Mark Cohen argues persuasively for Sherman's legacy as a touchstone of postwar humor and a turning point in Jewish American cultural history. With exclusive access to Allan Sherman's estate, Cohen has written the first biography of the manic, bacchanalian, and hugely creative artist who sold three million albums in just twelve months, yet died in obscurity a decade later at age 49. Comprehensive, dramatic, stylish, and tragic, Overweight Sensation is the definitive Sherman biography.--From publisher description.
