(John Sublett; born 19 February 1902 in Louisville, Kentucky, died 18 May 1986 in Los Angeles), American tap dancer and singer. Nicknamed “Bubber,” Bubbles is best known for his original portrayal of Sportin' Life in George Gershwin's Porgy and Bess (1935) and as one half of the famous singing-and-dancing comedy act of Buck and Bubbles. The act, which began when the ten-year-old Bubbles teamed with six-year-old Ford Lee (“Buck”) Washington, lasted almost fifty years. The two were featured in the Ziegfeld Follies of1931 and were the first black artists to appear at New York's Radio City Music Hall.
