The earnings will be donated to a charity that was founded by British artist’s father, said Bennett’s spokesman.
Mitch Winehouse, Winehouse’s father, established a foundation, Amy Winehouse Foundation, to help drug addicts.
This is one of the last recordings of the British artist.
Amy Winehouse died at the age of 27 years, on July 23. The official cause of death hasn’t yet been determined.
The song will appear on Bennett’s album, “Duets II”, which will be released on September 20.
