Billy Stewart (March 24, 1937 -- January 17, 1970)
While Stewart continued to record throughout the remainder of the 1960s on Chess without major success, his weight problem worsened and he developed diabetes. He suffered minor injuries in a motorcycle accident in 1969 and died the following January, just two months prior to his 33rd birthday. It happened when the car he was driving plunged into the Neuse River in Smithfield, North Carolina, killing him and three members of his band.
