Mitch Winehouse has told fans of his late daughter that he has spoken to her through a psychic.
He said he communicated with Amy Winehouse, who died last year, on Tuesday and she "is fully behind everything that we're doing and she's up in heaven waving her magic wand".
He was speaking at an event in New York to launch the US version of the late singer's charitable foundation and was joined by Winehouse's mother, Janis, and her younger brother, Alex.
They held a press conference in Joe's Pub, where Winehouse gave her first American performance on January 16, 2007.
The foundation was formally established in the UK last year and to date has allocated more than STG275,000 ($A426,753) to various charities, organisers said.
A brief film showing the foundation's British achievements was shown during the conference where the Winehouse family discussed their daughter's passion for wanting to help children.
The US foundation's aim is to "support and empower children in need through music therapy and music education".
The family announced a donation of $US10,000 ($A9,734) to the New Orleans Jazz Orchestra - first introduced to the Winehouses by CNN anchor Soledad O'Brien.
Mr Winehouse also performed four songs with a jazz band, at one point kissing his mobile phone which had a photo of his daughter on it.
He will release a book about his relationship with his daughter, who died of accidental alcohol poisoning on July 23 at her London home. It's titled Amy, My Daughter and will be released on June 26. All proceeds will benefit the foundation, he said.
The organisation also announced the Amy Winehouse Inspiration Awards and Gala, to be held on September 10 in New York.
