Hi There
dont quite see what you find weird here its a guy from Korea called Funtwo who has taken the Jerry C canon rock arrangement and in my humble opinion plays it better than Jerry......sure some of the sweeps are not to clever and a bit jumbled at times but its a pretty mean effort although I believe he has changed the key to C rather than the original D.There is also a fantastic version by a young guy called Mattrach who puts his own identity and style on the piece.
Not trying to be critical I just cant see what is so weird maybe I have missed the point somewhere....anyway good luck and tight strings
