Doris Day began her career as a big band singer in 1939.
Her popularity began to rise after her first hit recording,
"Sentimental Journey", in 1945.

After leaving the Les Brown & His Band of Renown
to try a solo career, she started her long-lasting
partnership with Columbia Records,
which would remain her only recording label.
The contract lasted from 1947 to 1967, and included more
than 650 recordings, making Day one of the most
popular and acclaimed singers of the 20th century.
