Walt Ribeiro is a musician. Walt is a Coulton fan. Walt also has access to an 80 piece orchestra. What happens when you mix the three together? You get Coulton's "Code Monkey" done in an orchestral fashion. I don't know if Joco has seen this yet, but I'm sure it will blow his mind. Another reason why CC rocks all things.
BTW, Walt is also trying his hand at filmmaking, hence the video with the song. It's cute, in a glo-wormy/monchichi-ish sort of way.
