Yeah - I'd say the right hand matches fairly well but the left hand not - left hand part on the audio is very rapid rhythm.
The music over that is definitely that part of "Do You Like Worms," but what is he *really* playing? I don't think it's possible to tell. Pretty sure the audio was played by someone on Malcolm Leo's staff just to provide a musical backing there. Like, the same source whence we get the piano versions of "Friends" and "Girl Don't Tell Me" and that piano-plus-vocal "Summer Means New Love."
I never bought that "pianist looked at what he was doing" thing...I mean, I don't think it's possible to tell; we never do get a long enough look at the keyboard itself.
