Beatrice Ruth Wain was an American Big Band-era singer and radio personality born in the Bronx, New York City. She had several hits with Larry Clinton and His Orchestra, including "My Reverie", "Deep Purple", and "Heart and Soul".

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.
