Sorry, kla4, but finger timing gets all messed up in Youtube videos (audio is rarely ever in good sync). You'll also notice it is a two camera shot, or more accurately, a one camera shot, shot twice

It is likely that one of the 'takes' was miming over the original track (actually, as he said that he had assembled this in Cakewalk, possibly both takes were mimed).
Plus, I've got that Roland file, and while there are a lot of similarities, there's a few significant differences. Just listen to the fill at 1:40. Thing is, either BOTH MIDI files copied Celine's version pretty faithfully, or if he used the Roland file, he certainly edited the bejeezus out of it!

Either way, it sounds great...
