I am a sucker for Schlager films, and with the 15 or so Schlagers I could have had an amusing 90 minutes. But why was that flimsy story added? Why not a film with only Schlagers. Without story we would have been spared quite a number of the cast: Teddy Stauffer - ex band leader of the 20's and 30's - acting as if he is in constant urinary trouble; boxer Bubi Scholz, who should have been k.o.-ed before shooting started (maybe he was, but managed to keep moving); Giorgia Moll playing the pretty girl without being convinced of it (she is right). At least there are Trude Herr and Rudolf Platte routinely taking care of some comedy.
As for the Schlagers, there are some bad ones: offensive Jan & Kjeld should have been tied up with the strings of their banjos; an abominable cover of Louis Prima's Buona Sera is sung by Rex Gildo; and if there had been one more rendering of the title song, I would have shot myself.
For Paul Martin this film is a very far cry from quality films like e.g. Der blonde Traum (1932), Glückskinder (1936), and even his films of the 50's. His direction here is not even routine anymore, it is simply chaotic; was he interested at all?
