As Long As They’re Happy (1955)

Jack Buchanan plays a stuffy British stockbroker whose home is thrown into chaos when a popular American singer (Jerry Wayne) comes to visit. His three daughters, one a bobby-soxer, another a budding existentialist and the third a cowboy's wife, are mad about the singer and go into a frenzy that drives their father crazy. Mom (Brenda De Banzie) thinks it's all harmless and sees it as a good opportunity to rib her fuddy-duddy husband. Diana Dors appears in a cameo role.
