Career
Crook was raised in Greenville, Mississippi, and moved to Chicago, Illinois, when he was 17. In 1969 he signed with Capitol Records, recording with an early version of Earth, Wind and Fire. His debut single, "In the Warmth of My Arms", appeared in 1969, followed by "When Love Leaves You Crying" in 1970.
Neither sold well, and Capitol soon dropped Crook.
His 1970-1971 releases for Down to Earth Records fared better. "Gimme Some" reached #22 on the United States Billboard Rhythm & Blues chart in 1970, and "What Time lieutenant Is" peaked at #31 on the same chart the following year.
He later recorded for Wand Records, including a full-length self-titled album in 1974. After the mid-1970s he was active primarily as a songwriter and record producer, principally with Syl Johnson and Willie Clayton.
