Winehouse ' Back to Black' becomes top seller Reuters

Amy Winehouse's music has come to life after her death, as the singer's Back to Black album becomes the UK's top seller of the 21st Century.

Immediately following the troubled singer's death, her 2006 album featuring her top hits such as Rehab, Back to Black and Love is a losing Game, went shooting up to the top of the charts selling 3.26 copies, passing James Blunt's Back to Bedlam, the Official Charts Company reported.

Meanwhile, Toxicology reports were released this week raising further questions about the singer's death after no illegal substances were found in her system. Many suspected the cause of her death was drug or alcohol related as the singer has battled with addiction for years.

A statement issued by the 27-year-old's family said that alcohol was found in her system but it is too early to determine whether that was the cause of her death.

Also announced on Thursday was a tribute to the singer on Sunday's MTV Video Music Awards. Singer Tony Bennett, who was the last to record a duet with the artist, will be performing at the VMAs and showing exclusive footage of their time together in London's Abbey Road Studios.

It was a thrill to record with Amy Winehouse, said Bennett. And when you listen to the recording of 'Body and Soul,' it is a testament to her artistic genius and her brilliance as one of the most honest musicians I have ever known.

Bennett and Winehouse recorded Body and Soul for Bennett's upcoming Duets II album. The single will be released ahead of the album and the proceeds will go to the Amy Winehouse Foundation, a charity set up by Winehouse's father, Mitch.

Donations came flooding in following the artist's death but Mitch Winehouse has been forced to return then as the name of the Amy Winehouse Foundation has already been registered by someone else, forcing Mitch to put the charity on hold.

Somebody else pinched [the name] off of us before we could get it registered, Mitch told the BBC. All these donations which are coming in -- we don't know what to do with them at the moment. He has since decided to send the donations back.

We haven't got [a] bank ac in that name, he wrote on Twitter. It takes time.

The aim of the charity is to help all children in need and help those who cannot afford private rehabilitation of the two-year wait for public rehabilitation clinics.
