A day after Lata Mangeshkar claimed that late singer Mohammed Rafi had apologised to her in writing, his son Shahid Rafi has refuted her, saying it was a "publicity stunt" and he might even take legal action. "My father was a national property. I am hurt and so are his fans. His fan following is much bigger than any other artist. If she can prove that my father had written an apology letter to her, then I am ready to apologise," Shahid told reporters. "Let her show the letter. My father passed away years ago, and now she is talking about this letter? People keep valuable documents for even fifty years. Why hasn't she retained the paper which would give her dignity," he said. In an interview to a newspaper, Lata was quoted as having said that she and Rafi fought over royalties. When Rafi had said that he would not sing with her at a meeting attended by other musicians, she had reportedly retaliated by saying that it was she who would not sing with him.
