Devout fans know the difference, but others have difficulty discerning B.B. King and Bo Diddley. Both men were born in Mississippi in the 1920s, both were raised by family members, both became legendary guitarists and toured extensively, and both were inducted into the Rock & Roll Hall of Fame in 1987.

Fifteen questions await you, and the answer to each is either B.B. or BO. A score of 8 or better is a "win." Good luck!
