My Wife Wants to Sing (1958)

Having been happily married for ten years, Gerda Wagner, devoted mother and housewife, suddenly gets it into her head that she would like a career as a pop star. She had singing lessons in the past and her voice is still beautiful. A chance meeting with the idolized Italian singer Fabiani, revives her stage fever - much to the annoyance of her husband Gustl Wagner, head of the records section at a department store.
