 Al Jolson dotted the "Kraft Music Hall" landscape, first as an occasional guest from 1933 to 1935, then later as the star and host from 1947 to 1949, while his sarcastic pianist and sidekick Oscar Levant piped in with his dry wit.Jolson kept working until shortly before his death in 1950, with these shows as some of his last.Many of the show's recurring jokes and funny remarks were about Jolson's education, his age and his relationships to women.
