The opening to Suite No. 1 looked easier than on chromatic free bass to be fair! Or maybe he just made it look easyJust watched the Galliano video - my schoolboy French can just about manage it! Watch one of the greatest accordionists that ever lived play the easiest quint scale in C major at 5.30 and the slight unevenness as he ends the first octave and begins the second in a way that no other instrument would do. You can see why if you look at the acrobatics his hand is having to do at that moment. Magnify that issue by 100 for us lesser mortals!
