Mark Twain wasn’t the only cultural icon born in Hannibal, Missouri. There was another fellow, a funny looking, wide-eyed guy who played and popularized the ukulele in the 1920s while selling millions of records, introduced the Gershwin classic “Fascinating Rhythm” from the Broadway stage, popularized the tune “Singin’ in the Rain” 20 years before Gene Kelly skipped through puddles, and was the winning voice of Jiminy Cricket, crooning the Disney anthem “When You Wish Upon a Star.”
