Amy Winehouse and Tony Bennett
The pair's duet is set to be released as a charity single.
It was one of Amy's last recordings before her death last month and Bennett has said that proceeds will go to the charity set up by her dad - to help those addicted to drugs.
"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, he told NBC .
The veteran crooner also said how Winehouse "sang beautifully" on the track, which has been named Body And Soul .
Meanwhile, the late star's family are awaiting the results of toxicology reports to determine her cause of death.
