Betty Jean Morris was an R&B singer with one known release on Capitol Records, “Shack Daddy” backed with “I Ain’t Gonna Mambo.” She was reportedly discovered by Jerry Lieber and Mike Stoller while singing in a Los Angles cafe, and the songwriting team wrote the two songs for her. “Shack Daddy” was a 12-bar blues, and “I Ain’t Gonna Mambo” was an effort to capitalize on a current fad for mambos. Billboard remarked that “the gal has a real wild style.”
