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.

Titled "Body and Soul'' Winehouse recorded the classic pop song with Bennett in March, reports The Telegraph.

Bennett recorded ''Body and Soul'' with Winehouse at the Abbey Road Studios in London, and has credited her for her abilities as a jazz singer.

Proceeds from Bennett and Winehouse's 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 Sept. 20.

"What's going to happen is that we're putting that [Body and Soul] out ahead of the album," Bennett told MTV.

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.

Grammy winner Winehouse was famed for her soulful voice, 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 planning to create a foundation in her name to help drug addicts.
