This special looks back at the greatest "crooners" and "canaries" of the 1940s, featuring the greatest vocalists of the period when they started their careers performing with orchestras and dance bands, with the most popular singers ultimately becoming stars on their own. Among the legendary artists and timeless hits included in the rare, vintage footage are Louis Armstrong, Perry Como, Doris Day, Helen Forest with the Harry James Orchestra, Peggy Lee with The Benny Goodman Orchestra, Johnny Mercer & Margaret Whiting, Jo Stafford & The Pied Pipers with the Tommy Dorsey Orchestra, and many more favorites from the World War II era. Hosted by Nick Clooney & Peter Marshall.
