Kitty Kallen was an American singer whose career spanned from the 1930s to the 1960s, to include the Swing era of the Big Band years, the post-World War II pop scene and the early years of rock 'n roll. Kallen performed with popular big band leaders of the 1940s, including Jimmy Dorsey and Harry James, before establishing a solo career.

A big band or jazz orchestra is a type of musical ensemble of jazz music that usually consists of ten or more musicians with four sections: saxophones, trumpets, trombones, and a rhythm section. Big bands originated during the early 1910s and dominated jazz in the early 1940s when swing was most popular. The term "big band" is also used to describe a genre of music, although this was not the only style of music played by big bands.
