When Jackson first toured in 1955 and 1956, she was placed on a bill with none other than Elvis Presley. The two hit it off almost immediately. Jackson said it was Presley, along with her father, who encouraged her to sing rockabilly.

In 1956, Jackson finally signed with Capitol, a relationship that lasted until the early '70s. Her recording career bounced back and forth between country and rockabilly; she did this by often putting one song in each style on either side of a single. Jackson cut the rockabilly hit "Fujiyama Mama" in 1958, which became a major success in Japan. Her version of "Let's Have a Party," which Elvis had cut earlier, was a U.S. Top 40 pop hit for her in 1960, after which she began calling her band the Party Timers. A year later, she was back in the country Top Ten with "Right or Wrong" and "In the Middle of a Heartache." In 1965, she topped the German charts with "Santa Domingo," sung in German. In 1966, she hit the U.S. Top 20 with "The Box It Came In" and "Tears Will Be the Chaser for Your Wine." Jackson's popularity continued through the end of the decade.

Jackson toured regularly, was twice nominated for a Grammy, and was a big attraction in Las Vegas from the mid-'50s into the '70s. She married IBM programmer Wendell Goodman in 1961, and instead of quitting the business -- as many women singers had done at the time -- Goodman gave up his job in order to manage his wife's career. He also packaged Jackson's syndicated TV show, Music Village. In 1971, Jackson and her husband became Christians, which she says saved their marriage. She released one gospel album on Capitol in 1972, Praise the Lord, before shifting to the Myrrh label for three more gospel albums. In 1977, she switched again, this time to Word Records, and released another two.

In the early '80s, Jackson was invited to Europe to play rockabilly and country festivals and to record. She's since been back numerous times. More recently, American country artists Pam Tillis, Jann Browne, and Rosie Flores have acknowledged Jackson as a major influence. In 1995, Flores released a rockabilly album, Rockabilly Filly, and invited Jackson, her longtime idol, to sing two duets on it with her. Jackson embarked on a major U.S. tour with Flores later that year. It was her first secular tour in this country since the '70s, not to mention her first time back in a nightclub atmosphere. Jackson returned to the studio in 2010 to begin work on a new album. Produced by Jack White and featuring a band comprised of the White Stripes frontman, his wife Karen Elson, various Raconteurs, My Morning Jacket's Carl Broemel, and a host of others, The Party Ain't Over arrived in early 2011.
