Being labeled as her final studio performance, a video was released today — on what would have been Amy Winehouse's 28th birthday — of a duet between her and Tony Bennett. The song, "Body and Soul," was recorded in March and will be released on Sept. 20 on Bennett's Duets II album. All proceeds from the single will benefit the Amy Winehouse Foundation. Winehouse died in July — the cause has not yet been determined.
