Here's singer Jo Stafford performing one of her earliest solo hits "The Gentleman Is A Dope" at a concert during the 1950s. She had first recorded this song in 1947.
Jo Elizabeth Stafford (November 12, 1917 – July 16, 2008) was an American singer of traditional pop music and jazz standards whose career ran from the late 1930s to the early 1960s. Stafford was greatly admired for the purity of her voice and was considered one of the most versatile vocalists of the era. She was also viewed as a pioneer of modern musical parody, having won a Grammy Award for Best Comedy Album in 1961 (with husband Paul Weston) for their album Jonathan and Darlene Edwards in Paris. She was also the first woman to have a No 1 on the UK Singles Chart. Stafford's work in radio, television and music is recognized by three stars on the Hollywood Walk of Fame.
