A musician whose songs helped teach children on ABC's "Schoolhouse Rock" has died.
His son, Chris, says 94-year-old Bob Dorough died of natural causes Monday at his home in Mount Bethel, Pennsylvania.
According to his biography, the jazz musician "set the multiplication tables to music" as musical director for the educational cartoon series between 1973 and 1985.
