Aha, this made me smile. Dan plays this after saying "I just had another person say 'who are you?'" "Who … Are You?" is the name of part of the Final Fantasy VII soundtrack, and the excerpt he plays is another part of that soundtrack ("The Nightmare Begins"). I love how he knows it so well that those words immediately make him think of it. even in 2012anathema wrote:52:20 plays a few seconds of a piece I don’t recognize.
I just found a clip of Dan playing the whole excerpt, although I've no idea where it's from (another liveshow I guess?).
