Without any doubt, The Andrews Sisters were the Forties" most famous female singing-group. They recorded 224 sides on the DECCA label from 1937 to 1951 of which no fewer than 113 reached the American charts and 19 were gold records. They had contributed not only dynamism and joie de vivre to the genre, but also up-tempo rhythms and sophisticated, interwoven vocal harmonies that were jazzy. Their smiles and optimism largely contributed to the hope that prevailed in America throughout the war, and it earned them the nickname of "America"s Wartime Sweethearts".
