I wonder if this was played live remotely by a person or if it was recorded and rehearsed. In either case, awesome, but turn these five stars into all the stars in Marioworld if it was live.
.. the guy who's not any better at mario than I am, that is.. not the violinist :)
Let me give a quick shout out to my friends in the Portland Cello Project, who do a really cool cover of this as well. Couldn't find a good version without people talking while recording on their phones, etc.. but check them out. In either case, I don't think anything less than a bullet-bill will get this fucking song out of my head.
