Anderson – best known for her 1971 hit "(I Never Promised You A) Rose Garden" – died of a heart attack Thursday night at Vanderbilt University Medical Center, where she was being treated for pneumonia, The Tennessean reports.
The singer was born in Grand Forks, North Dakota, and grew up in Sacramento, California, with a used car salesman dad and part-time songwriter mom, who wrote Merle Haggard's hit "(All My Friends Are Gonna Be) Strangers."
Anderson got her start in the late '60s on The Lawrence Welk Show, as well as performing as a musical guest for both Ed Sullivan and Dean Martin.
In 1968, Anderson married writer-producer Glenn Sutton, with whom she welcomed a daughter, Lisa. After divorcing her first husband in 1977, she wed oilman and rancher Harold "Spook" Stream III a year later. Anderson and Stream went on to have two kids, William Gray and Bunny, before splitting in 1982.
In recent years, Anderson struggled with alcohol, having been charged with DUI in 2004 then again in 2014. Last month, she released her first gospel album, Bridges.
Anderson is survived by her father and three children.
Tim McGraw shared a tribute to Anderson on Friday.
