Bye Bye Blues(1989)

During World War II, Daisy Cooper returns home to Canada with her children after her British husband, soldier Teddy, is assigned to Singapore. With the help of trombonist Max Gramley, Daisy's amateurish piano and vocal skills improve, and soon she is supporting her family with her performances. Unsure whether Teddy is alive or dead, Daisy is torn between staying faithful and giving in to her growing feelings for Max.
