The professional career of Carl Sims began when he was only sixteen years old, as the Lead Singer for the Original Bar-Kays back in the middle Sixties. The Bar-Kays took Arthur Conley's place as opening act for the Otis Redding Revue. A plane crash in Milwaukee, Wi. in 1967 killed Otis and several of the Bar-Kays. Carl along with James Alexander the Bass Player for the group luckily took a commercial flight out of Cleveland, OH to join the group in Milwaukee, because there was no room on Otis's private plane. Carl remembers, having to identify the bodies of the Band members. After returning to Memphis along with the surviving members Ben Cauley (Trumpet player) and James Alexander what was left of the Bar-Kays went there separate ways.

Carl began his solo career with a couple of Hits "Trapped" and "17 Days of Loving", on Paula-Jewel Records. From there he went to MALACO Records where he was Label mates with the Late Great Johnnie Taylor and the Late Great Z.Z. Hill, along with Little Milton Campbell, Bobby Rush, Ms. Denise LaSalle and Bobby Bland.
