Tony Bennett's studio has released the single of Body and Soul that features the 85-year-old singing alongside Amy Winehouse. It is believed to be one of the last recording sessions by Winehouse, who died July 23. Bennett, a great survivor himself, was one of Winehouse's musical heroes.

On Wednesday - which would have been her 28th birthday - her family launched The Amy Winehouse Foundation. All the proceeds of the Body and Soul single go to the foundation, which will support a range of smaller charities that work with children. Her father, Mitch Winehouse, said the soul diva had a passion for children and would have wanted to help young people struggling with low incomes, addiction and health problems.

Winehouse Sr. has made a series of speculations about what might have ended Amy's life, including statements Wednesday that she might have had a seizure related to alcohol detoxification. The grieving father is attempting to reclaim her reputation, saying she had given up drugs three years ago, though continued to battle with alcohol. An autopsy and toxicology reports were, in fact, inconclusive. An inquest scheduled for next month is expected to establish a cause of death.

Bennett has spoken graciously about Winehouse's talent. Body and Soul will be part of his Duets II album, which features him with a variety of younger stars, including k.d. lang, Lady Gaga, Andrea Bocelli and Michael Bubl.
