According to her rep, Anderson passed away from cardiac arrest at Vanderbilt University Medical Center in Nashville.
Anderson began her career in the 1960s, releasing a string of successful singles, including "If I Kiss You (Will You Go Away) and "That's a No-No," along with appearances on The Lawrence Welk Show. However, it wasn't until she released "Rose Garden" that she became a bonafide star, winning a Grammy and Country Music Award for the song in 1971.
She continued to dominate the charts following "Rose Garden," releasing a total of five No. 1 songs in her career. Anderson released her final album, Bridges, in July.
Anderson is survived by her father, singer Casey Anderson, partner Mentor Williams, and children Lisa Sutton, Melissa Hempel and Gray Stream.
