Lovely Joan Staley was born Joan McConchie on May 20, 1940 in Minneapolis, Minnesota and started taking violin lessons by the time she was three years old. Living in Los Angeles, her prodigious talent was obvious. She soon joined a baby orchestra in Los Angeles and, within a few years, became a Junior Symphony performer at age six. She also made her unbilled specialty debut on film as a child violinist in The Emperor Waltz (1948), starring Bing Crosby and Joan Fontaine.

Her father's business had the family traveling throughout Europe growing up but she later relocated to California and briefly enrolled at Chapman College in the Los Angeles area. Becoming a stunning, statuesque beauty, she re-directed herself back to a career in show business, singing backup on records for Sam Phillips and working as a secretary to make ends meet while appearing in local L.A. stage productions.
