Dude! before I watched that video I think "GODDAMNIT if he plays it with his A**!"
Damnit! what's up with that Mario. I bet its the most played piece of music on youtube...
Now I gotta start thinking What instrument should I learn it on... It has to have some crazy twist like two guitars or blind folded...
NOw that super fast mario is just silly
Edit. Here's one on violin too...
