That's a great vid DV! I had never seen or heard somebody playing on Mozart's piano until that vid. That is amazing. Very nice.
Also - somebody in that youtube thread from a couple years back wrote:
time 0:49 - Mozart as a ghost be like: How dare you put your elbow on my piano!? *Starts laughing cuz duh, he's Mozart.*
If he were to put his head on the piano, then that could possibly be a historical world's first !!!!! First to put our head on Mozart's piano. Even a big toe --- putting on it -- historically first person to do that hehe.
