Paul Butterfield From Wikipedia, the free encyclopedia Paul Butterfield (December 17, 1942 – May 4, 1987) was an American blues harmonica player and singer, and one of the earliest white exponents of the Chicago-originated electric blues style. Paul Butterfield, a lawyer’s son, was born and grew up in Chicago. After studying classical flute as a teen, he developed a love for the blues harmonica, and hooked up with white, blues-loving, University of Chicago physics student Elvin Bishop (later of “Fooled Around and Fell In Love” fame).
