MEMPHIS, Tenn. (AP) — Memphis musician B.B. Cunningham scored with a classic garage rock song and toured with Jerry Lee Lewis, but he also enjoyed his side job as a security guard because he liked standing up for other people. On Sunday, he died doing just that.

Cunningham co-wrote the 1967 hit “Let It Out (Let It All Hang Out)” for his band the Hombres and toured more recently with Lewis. The 70-year-old keyboardist, bassist and singer’s other job as a uniformed security guard provided a steady paycheck, his son said.
