At the beginning of her career, in 1958, she was working as a warden at Ulleråkers sjukhus, a mental institution and hospital, where she used to play her guitar during breaks to entertain her colleagues. The two artists made a bet with each other, that whichever of them won a significant song competition would also have exclusive right to the stage name. After winning the song competition, Jacobsson travelled to
Stockholm with her father, hoping to perform at the popular Nalens dance hall. She would later recall her father talking with the manager of Nalens, Topsy Lindblom, who first stated that "lots of daughters can sing", but then relented and asked her to come in when Jacobsson's father stated "Yes but she can sing rock". Both prior to and after her time in Hafvsbandet, Rock-Olga performed with another rock band called Rockfolket ("The Rock People"). In later years, she still travelled across Sweden performing as many as 30 concerts per year, usually at retirement homes where "What You've Done to Me" was always part of her set. ==Death==
