Lin-Manuel Miranda, who is busier than George R.R. Martin, but somehow more productive, stopped by The Late Show last night to gab it up with Stephen Colbert and to try out a sample of a his musical about the very real Button Gwinnett. In addition to watching Stephen Colbert don a wig and toss off a few John Adams disses, you’re also going to want to watch his full interview with Miranda, if only for the chance to watch the pair sing a few bars from The Man of La Mancha (skip to 7:20 in the video below to see that, though it’s worth watching the whole thing).
