Believe it or not, it was a duet with Tony Bennett and it's coming out tomorrow. Here's the scoop from the RAMP Newsletter...
"Tomorrow, Sept. 14, marks what would have been Amy Winehouse's 28th birthday. To commemorate that occasion and to pay tribute to an amazing talent who lives on via her musical legacy, RPM and Columbia Records are releasing the single and the video for "Body and Soul," Amy's duet with the legendary Tony Bennett, one of 17 tracks that appears on his forthcoming Duets II album. "Body and Soul" was recorded on March 23 at the historic Abbey Road Studios in London and holds the distinction of being Winehouse's final recording before her untimely death on July 23."
