In 1965, while spending some time in Tennessee State Penitentiary in Nashville for car theft, he met Johnny Bragg, the founder of The Prisonaires vocal group.
After the plane crash that claimed the lives of Otis Redding and four members of The Bar-Kays, Colbert joined the reconstituted group as lead singer, and performed with them for several months, but did not record.
[4] In 1968, after Sam & Dave had moved from Stax to Atlantic Records, Porter and his songwriting and production partner Isaac Hayes decided to put together a new vocal group of two men and two women.
They recruited Blackfoot, together with Norman West, Anita Louis, and Shelbra Bennett, to form The Soul Children.
Blackfoot worked with bands in the Memphis area, and recorded solo for the local Prime Cut label.
In 2007, Blackfoot and West reformed the Soul Children, with Hines and fourth member Cassandra Graham.
