Joe Cobb and Don Cornelius met when they were both working at WVON, the Black radio station in Chicago, back in the 1960s. Cornelius used that broadcasting experience for the 1971 launch of Soul Train, a groundbreaking TV dance show highlighting Black youth, music and fashion. But it was at WVON when the 22-year-old Cobb first voiced his now famous scream of the phrase “soul train” to open the show.
