The answer is NO for a commercial score, which never takes into account all the improvisation ... and there's a lot of that in this live show. Then there's the interpretation and its ...it's up to each person to decide how to play. The commercial score is a guide, and everyone can do what they like with it, without distorting the author's idea too much. After that, you can always ask a super-professional to give you a millimetre-by-millimetre account of everything that's played, even ... just the accordionist's intro... and I'm not sure it's possible to imitate him afterwards, even when faced with a score full of notes. (My own opinion: I don't know your reading and interpreting skills).
