Scott Cameron, 76, who managed the careers of blues greats Muddy Waters, Willie Dixon, and others in the 1970s and 1980s and played a key role in winning back ownership rights and royalties for blues performers, died Feb. 19 in a Springfield, Mo., hospice facility.
The cause was lung cancer, said his daughter, Manda Cameron-Hussain.
One of Mr. Cameron's moves was against members of Led Zeppelin, who recorded two Dixon numbers on its 1969 debut album, crediting the songwriter. But the follow-up album the same year included one of the group's biggest hits, "Whole Lotta Love," credited to members of the band. A lawsuit accusing the band of copyright infringement was settled out of court.
