This is a video of musician Jason Paige rerecording the Pokemon theme song he originally recorded for the cartoon way back in 1998 and accepted a one-time payment for so he receives no royalties. He really gives it his all. And by gives it his all I mean makes a lot of faces. There's a certain intensity to his performance that you can't find anywhere else outside of a regional air-guitar competition.
Keep going for the video.
Thanks to Bri, who agrees the song needs more maraca.
