Amy Winehouse, Tony Bennett Amy Winehouse, Tony Bennett

Amy Winehouse and Tony Bennett's "Body and Soul" duet will be released as a charity single benefiting a foundation being set up in her name.

Winehouse and Bennett recorded the track earlier this year for his upcoming Duets II album, which was the last record the singer made before her July 23 death.

"We're putting [the song] out ahead of the album [due out Sept. 20] 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," Bennett said on the Today show, adding that Winehouse "sang beautifully."

Winehouse's father, Mitch, announced at her funeral last week that  he plans to start the Amy Winehouse Foundation to help those struggling with addiction. The foundation will also benefit children and horses — two of Winehouse's passions.
