PRESS ASSOCIATION -- Amy Winehouse's duet with Tony Bennett - one of her last recordings - will be released as a charity single, according to reports.
The veteran crooner told NBC's Today programme royalties from the song, Body And Soul, would go to the foundation set up in Amy's name by her father.
He said Amy, who died last month, "sang beautifully" on the track which features on his new album of duets, and added: "Actually what's going to happen is that we're putting that out ahead of the album. And it's going to a foundation that her father started to teach all the young children not to take drugs, and all the royalties of the record will go to that."
Mitch Winehouse said the foundation would support people struggling with drink and drugs and "help thousands of people".
His daughter was found dead at her north London home after a long and public battle with addiction.
Writing on Twitter, Mitch said: "The foundation is going to help thousands of people. That is Amy's legacy."
In a eulogy at his daughter's funeral, he said the foundation would be "something to help the things she loved - children, horses, but also to help those struggling with substance abuse".
Mitch visited Parliament earlier this week to plead with the Government to reform drug rehabilitation centres for youngsters.
The 27-year-old singer's family are awaiting the results of toxicology tests to establish the cause of her death.
Because of her battles with drink and drugs, news of her death was quickly followed by suggestions it could be related to one or the other. A post-mortem examination proved inconclusive and an inquest was opened and adjourned with no cause of death given.
