Four unemployed jazz musicians seize the chance of their life by saving the day when opening night celebrations at a night club go wrong. One of them falls in love with a schoolteacher who dreams of fame as a singer … In this, her vibrant film debut, Swedish singer Siw Malmkvist, who had a hit in Germany with “Liebeskummer lohnt sich nicht”, warbles her way around Copenhagen locations, including the floral splendours of the Tivoli Gardens. In 1960, the German movie journal Film-Dienst wrote, “This import from Denmark’s modest film production has the charm of a spring day.

It is permeated with such a sense of unconstrained youth that the heart swells”.
