Watch the video premiere of Josh and Tony Bennett performing "This Is All I Ask" from Bennett's Duets II.

"Josh Groban is a very smart and and extremely nice person," Tony Bennett tells AOL Music. "He was very comfortable recording live in the studio, which is how I work, but he told me he normally has a big orchestra involved so it was a new experience for him to work with a jazz quartet for our duet of 'This Is All I Ask.' I think he did a beautiful job finding the right balance working with a quartet. It's a song that I introduced in 1963 and I thoroughly enjoyed recording it again with Josh Groban almost 50 years later."
