Is there any article or paper that describes what Thomas Sargent thinks of New Keynesian economics/models? Is there any article or paper that describes what Thomas Sargent thinks of New Keynesian economics/models?

I am asking this question, because we all know what Thomas Sargent thinks of Old Keynesian economics, but I can't find what he thinks of New Keynesians that involve sticky price (well, Calvo/Rotemberg/etc. methods) and imperfect competition.
This journal article (Oct 29-2011,) has parts from a telephone conversation of the journalist with Sargent:

Although none of it mentions "New-Keynsian", there are some interesting points, like


  "Professor Sargent said he felt insulted by people who call him
  “non-Keynesian” or “right wing,” terms that, he said, are based on a
  misunderstanding of his thinking... He’s a Democrat, he said, “a fiscally conservative, socially liberal Democrat,” adding, “I
  think that budget constraints are really central.”"


On Keynes?


  "The “non-Keynesian” label irks him particularly. “That’s just off
  base,” he said. “Keynes was a very good economist. He was brilliant.
  He had wonderful insights. His work has inspired me many times.”"


So are we to believe that Sargent is a "Keynesian"?


  "Today, Professor Sargent says that in some ways he actually is a
  Keynesian, but he qualified that claim, too. “I’m happy to say I am a
  Harrison-Kreps-Keynesian,” he said, citing work by two scholars at
  Stanford, J. Michael Harrison and David M. Kreps. They developed a
  theory of speculative investor behavior and stock-bubble formation
  that subtly modifies rational expectations “in a beautiful way” and
  “captures Keynes’s argument, makes it rigorous, and pushes it
  further,” he said."
