Tony Bennett to Release Duet With Amy Winehouse

The late Amy Winehouse's final recording, a duet with the great Tony Bennett, will be released as a charity single for a foundation set up in her name.

"Body and Soul" will go on sale in September, with all proceeds going to the newly established Amy Winehouse Foundation, according to her dad, Mitch.

Mitch Winehouse was always Amy's biggest supporter, having tried for years to get her help. Now that she's gone, he's advocating important causes.

Winehouse and Bennett, who just turned 85 (!), recorded the pop song in March at London's Abbey Road Studios for Tony's forthcoming Duets II album.

The 27-year-old Winehouse, who famously struggled in recent years with drug and alcohol addiction, was found dead at her London home July 23.

Her cause of death remains inconclusive, but family believes that an abrupt alcohol withdrawal, rather than a drug overdose, was likely to blame.
