McCain on Romney

From Byron York's piece on the senator, in the latest (not-online) National Review:

In the van, I bring up Romney's statement, made the day before, that as president he might order a "bombardment of some kind" against Iran. The word "bombardment" strikes the McCain group as somewhat quaint, and top aide Mark Salter, sitting in the back seat, says Romney must have just read a book about Francis Scott Key and the assault on Fort McHenry. With that, McCain breaks into open ridicule of Romney, bellow out mock commands:

"Bring up the mortars!"

"Don't tear that tattered ensign down!"

"All those forward, go aft!"

I just wish I knew what McCain said to his aides after Romney's "double Guantanamo" line.
