A duet between jazz great Tony Bennett and the late singer Amy Winehouse is being released as a single to benefit a charity established by her father, Bennett's spokeswoman said on Wednesday.
The classic pop standard "Body and Soul" that Winehouse recorded with Bennett in March is one of her last works. She died unexpectedly at age 27 on July 23, after a long battle with alcohol and drugs.
An official cause of death for Winehouse has not been determined. Her father, Mitch, is creating a foundation in her name to help drug addicts.
Proceeds from Bennett and Winehouse's "Body and Soul" recording, which is being released as a single, will go to the foundation, said Liz Rosenberg, a spokeswoman for Bennett.
The song will also appear on Bennett's "Duets II" CD to be released on September 20.
Bennett, a Grammy winning jazz legend whose biggest songs include "I Left My Heart in San Francisco" and "Rags to Riches," celebrated his 85th birthday on Wednesday.
He recorded "Body and Soul" with Winehouse at the Abbey Road Studios in London, and has credited her for her abilities as a jazz singer.
Grammy winner Winehouse was famed for her black beehive hair and soulful voice, and is best known for her 2006 song "Rehab" that summed up her struggles with addiction.
