Sweden 1945 when Europe finally reached the end of the war

Watching a Swedish tv show and I'm a sucker for history and how things have been before my time. My grandmother was a toddler during world War 2 and so I try to imagine my great grandmother's life when they moved to Sweden from Finland at that time.

Something I envy from the 50's is the way people partied. Jazz parties and the way they danced, it was real move and grove there. The men actually danced and swung you around. It looks so incredibly fun!
