This is such a great thing to exist.
It's staged, of course. I'm pretty sure of this for several small, geeky reasons, the most pressing of which is that Disney wouldn't allow a full-blown, Main-Street-blocking musical performance (done by alluding to their music and characters, to boot) to spontaneously appear without their permission. This would be a great little "random" thing to happen during their "Make Dreams Come True / Celebrate Today" theme of 2009.
Also, these people are miked; obviously they must have had access to their sound system. They had CD accompaniment and a video team, too. Now, maybe it could have been a real proposal if the man proposing was a fairly high-ranking employee... but I digress.
GUH.
