Mercy Dee Walton (August 3, 1915 – December 2, 1962) was an American jump blues pianist, singer and songwriter, whose compositions went from blues to R&B numbers. According to journalist Tony Russell in his book The Blues - From Robert Johnson to Robert Cray, "Walton created a series of memorable blues about the unattractiveness of rural life, sardonically aimed at the black migrant workers in southern California who constituted his typical audience".
