 You know, in listening to that Don Juan fantasy, it was almost more Liszt than Mozart. The tunes, of course, were by Mozart, but Liszt did so much transformation of them. Let's hear some Mozart himself. In fact, Mozart written at around exactly the same time as he was writing the opera Don Giovanni. This is a sonata from 1788, sonata in F major, Kershaw 547. Just to show you how close it was, Don Giovanni is Kershaw 527.
