"What a talent."
Legendary crooner Tony Bennett has recorded albums with Amy and Gaga, and has previously revealed his regrets over not trying to help Amy before she died.
They recorded the Grammy-winning duet Body and Soul together in 2011 and Bennett , 90, says in his memoir, Just Getting Started, that he is haunted by his failure to act.
Confessing that he had battled booze and drugs himself, he wrote: “Should I have told her that I’d contended a little bit myself and knew how you can fall into a bad cycle, but I also knew that you could bring yourself back?
“Would it have made a difference if someone she considered an idol had said to her something like, ‘You’re my idol. You are a once-in-a-lifetime talent. Please don’t take that from the world’?”
While he had heard about the Rehab singer’s battles with addiction, he saw no sign of it when they worked together in Abbey Road Studios.

“Amy was engaging, funny, charming, and utterly professional but a little bit shy,” he wrote. “She said she was nervous because she had never recorded a song with someone she considered to be one of her idols.”
