Hello,
There is currently an search online to find more info about this lost song:
During the search, two people claimed they heard this song in a movie.
One person who claims to have watched this movie in 2008 described it as post-WW2 American movie that focused on the life of people after the war.
Main character is a woman who is a clothes designer and in one scene she was scolded by the supervisor of the dressmaking shop she works at.
Does anyone recall ever watching a movie that sounds as described and has a song that I posted link of?
