Short answers, pulled from the story.
Jocko Henderson was an American radio disc jockey, businessman, and hip hop music pioneer born on the 8th of March 1918 in Baltimore, Maryland. Questlove described him in a 2013 interview as "unofficially the first MC" and cited him as a major influence on the earliest rap and hip-hop in Philadelphia in the late 1970s.
Jocko's Rocket Ship Show was a radio program Henderson hosted from 1954 to 1964 on New York stations WOV and WADO and Philadelphia stations WHAT and WDAS. It was an early conduit for rock and roll and featured Henderson's signature style of rhythmic patter and fast-talking jive.
Henderson sold the publishing rights to songs such as "Baby It's You" and "Will You Love Me Tomorrow," which Scepter Records had given him, rather than hold onto them. He made this decision specifically to avoid the fate of New York disc jockey Alan Freed, who was convicted of two counts of commercial bribery during the payola congressional hearings that began in 1959.
Henderson released "A Little Bit Of Everything" on Wand Records in 1961, "Rhythm Talk" and "The Rocketship" on Philadelphia International in 1979, and "Everybody's Uptight (Trying to Get Their Money Right)" on Sugar Hill Records in 1983. Scepter Records and Wand also created greatest hits collections called Jocko's Show Stoppers and Jocko's Rocket to the Stars.
Henderson broadcast on stations in Philadelphia, New York, Baltimore, St. Louis, Detroit, Miami, and Boston. His home stations included WSID in Baltimore, and WHAT, WDAS in Philadelphia, and WOV and WADO in New York.
Jocko Henderson died on the 15th of July 2000 after a long battle with cancer and diabetes. He was interred at West Laurel Hill Cemetery in Bala Cynwyd, Pennsylvania.
