As a pop singer, Lawrence got her start as one of the scores of hopefuls on the syndicated Johnny Mann's Stand Up And Cheer program. However, she is most known for her number-one hit, "The Night the Lights Went Out in Georgia", a song written by her first husband Bobby Russell, which was released on Bell Records in November 1972. It sold over two million copies and was awarded a gold disc by the Recording Industry Association of America in April 1973. During the last episode of the sixth season of The Carol Burnett Show (March 24, 1973), Lawrence received her gold record by surprise from Carol Burnett. Her first LP, The Night the Lights Went Out in Georgia, was issued soon after the single went gold in April 1973. "He Did With Me", Lawrence's followup to "The Night the Lights Went
Out in Georgia", reached number 75 in the United States, although it reached the top 20 of the adult contemporary music charts and also became her biggest hit in Australia, peaking at number one there in November 1973. She followed it up there with "Ships in the Night" (1974). In the fall of 1975, Lawrence managed one last minor U.S. chart entry on the Private Stock label with "The Other Woman" (number 81). In 1974, she recorded her second LP for Bell Records, Ships in the Night. The label was in the process of being bought out by Arista, and the LP was not released in the U.S. The LP was, however, released in Australia, where she continued to have chart success. Lawrence's first two LPs were released as a single CD with bonus tracks on April 1, 2014, by Real Gone Music. She released a disco album entitled Newborn Woman late in 1979. The album produced the minor disco hit "Don't Stop the Music".
