Drillinge an Bord Banda sonora (1959) BSO

Eduard, Otto and Heinz are identical triplets. Without knowledge of the others, the youngest of them uses an ad text of one brother and a melody of the other to compose a song for a pop-song contest. When he wins a cruise as the first price, the brothers enter a claim for it. So all of them go on vacation - with only one ticket. Even more confusion arises, when a detective on board sees through their game and suspects them to be a notorious gangster trio.
