My sister and mom and I can NOT get enough of this. Jim Carrey is pure genius. How does he sing this? We are trying to figure out if he practiced these exact intervals or if it was entirely improvised… It's just that it is so perfectly f-d up, and impossible to replicate with precision. I've tried over 100 times. He's doing some wildly weird stuff. We were trying to learn it well enough so we could score it. Impossible. If any of you can score down to the quarter note, I will send you the biggest present. I want to create a harmony line for this White Christmas rendition and sing it with Jim Carrey one day.
