Recently, Jerry C, or Jerry Chang, a Taiwanese, done a rock version of Canon and posted it on Youtube. It was very good. He has since been appearing in a number of Taiwan variety shows.

It soon caught on, and guitarists all over the way is doing a cover of it and post it in Youtube as well. All of them creditted him.

So far, my favourite are these 3. Alotta people say the Funtwo is the best. He's a Korean. At 1st, he tried to hide his identify, cap cover face, etc. But he has since been unvieled in Korean variety shows as well.
