WIKIPEDIA:

“ Al Jolson (May 26, 1886 – October 23, 1950) was an American singer, comedian, and actor. In his heyday, he was dubbed "The World's Greatest Entertainer".
His performing style was brash and extroverted, and he popularized a large number of songs that benefited from his "shamelessly sentimental, melodramatic approach". Numerous well-known singers were influenced by his music, including Bing Crosby Judy Garland, rock and country entertainer Jerry Lee Lewis, and Bob Dylan, who once referred to him as "somebody whose life I can feel". Broadway critic Gilbert Seldes compared him to "the Greek God Pan", claiming that Jolson represented "the concentration of our national health and gaiety."
In the 1930s, he was America's most famous and highest paid entertainer. Between 1911 and 1928, Jolson had nine sell-out Winter Garden shows in a row, more than 80 hit records, and 16 national and international tours. Although he's best remembered today as the star in the first (full length) talking movie, The Jazz Singer in 1927, he later starred in a series of successful musical films throughout the 1930s. After a period of inactivity, his stardom returned with the 1946 Oscar-winning biographical film, The Jolson Story. Larry [......] ”
