A short clip of Amy Winehouse's duet with jazz legend Tony Bennett has appeared online.

The song, called Body And Soul, will be released on 20 September with proceeds going to a foundation set up by Amy's father Mitch.

It will also feature on Tony Bennett's upcoming Duets album.

Recorded at London's Abbey Road Studios in March, it was one of the singer's last recordings before her death on 23 July.

'Fitting' tribute

When details of the release were announced Mitch Winehouse said in a statement he "couldn't be happier".

He added: "Amy was so excited to be working with Tony Bennett and really looking forward to her fans hearing this new recording.

"The fact that Amy's voice is sounding as amazing and beautiful as ever and she is singing with the great Tony Bennett seems the most fitting tribute of all at this very difficult time."

Last week Mitch Winehouse told Newsbeat he was having difficulties setting up The Amy Winehouse Foundation as someone else had registered the name.

He said: "Somebody else pinched it off us before we could get it registered."

However, writing on Twitter yesterday (22 August), he posted an update: "It seems we have got our foundation back. I will update you all tomorrow. Very positive."
