Griffith passed away in Nashville, Tennessee, according to her management company. A representative for Gold Mountain Media did not give a cause for her death.
“It was Nanci’s wish that no further formal statement or press release happen for a week following her passing,” the representative said.
Griffith was a Texas-born singer whose popular recordings include “Love at the Five and Dime,” “Once in a Very Blue Moon” and “Outbound Plane.”
She survived thyroid and breast cancer, which she was diagnosed with in the late 1990s.
