Teacher Zita Plays Waltz in D flat major by Chopin! (This is comedy!) :)
This is also called the "Minute Waltz", but Chopin did not really mean for it to be played in 1 minute! Good thing, because I could barely do it in 1 minute and 25 seconds! I think I prefer 2 minutes played more cleanly. But here is a video for your amusement.
