Jo Elizabeth Stafford (November 12, 1917 – July 16, 2008) was an American singer of traditional pop music and occasional actress, whose career spanned five decades from the late 1930s to the early 1980s. Admired for the purity of her voice, she was considered one of the most versatile vocalists of the era. Her 1952 song "You Belong to Me" topped the charts in the United States and United Kingdom, and made her the first woman to have a No. 1 hit on the UK Singles Chart. She was a 1961 Grammy Award winner for an album of comedic interpretations of popular songs produced with her second husband, Paul Weston.
Born in Coalinga, California, Stafford made her first musical appearance at age twelve. After graduating high school she joined her two older sisters to form a vocal trio named The Stafford Sisters, who enjoyed moderate success on radio and in film. In 1938, while the sisters were part of the cast of Twentieth Century Fox's production of Alexander's Ragtime Band, Stafford met the future members of The Pied Pipers and became the group's lead singer. Bandleader Tommy Dorsey hired them in 1939 to perform backup vocals for his orchestra.
